+
+## MARC syntax in the MarcEditor
+
+Understanding the layout of MARC data in the MarcEditor is key to using the program's tools successfully. For instance, in some tools it is important to specify a field's indicators directly preceeding the first subfield. Throughout this workshop we will highlight how different tools rely on this syntax to apply edits.
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+The MarcEditor divides a file of MARC records into 'pages' of 100 records. You can scroll up and down the page of MARC records using the scroll bar as usual, but to see the next 100 records you need to use the Next/Previous page controls which are at the bottom left of the screen. The MarcEditor can handle very large files of MARC records, because it never tries to load all the records at the same time.
+
+## Setting MarcEditor Preferences
+
+You can adjust the number of records displayed per 'page' through the MarcEditor preferences which can be accessed through the Edit → Preferences menu option from the MarcEditor, or through the 'Settings' icon on the opening screen of MarcEdit.
+
+Within the MarcEditor preferences you can adjust the font and font size within the MarcEditor. You can also set your character encoding defaults. If you navigate to File Associations within the Preferences window, you can select Associate (`*.mrc`) files with the MarcBreaker and Associate (`*.mrk`) files with the MarcEditor. Setting these file associations will make it easy to break `.mrc` files and edit `.mrk` files.
+
+If you change your preferences for the MarcEditor, the tool used to work with MARC data, you can always go back to the default settings.
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Reset settings for the MarcEditor in Preferences
+
+1. Click Edit → Preferences
+2. Select "MarcEditor" in the Preferences window in the left hand pane
+3. In the right hand pane, select Set Defaults for either font or font size
+4. Click Ok

+
+## Profiling your MARC data
+
+The MarcEditor provides multiple reporting options and tools to help you profile your MARC data and understand the contents of your file. Reports are located under the Reports tab.
+
+### Overview reports
+
+The `Material Type Report` can be used to identify the types of resources described in your MARC file. This report is helpful when you're uncertain of what resources are represented in your file, or to locate potential errors.
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Run Material Type Report
+
+To run the Material Type Report
+
+1. Click Reports
+2. Select Material Type Report
+3. Click Generate Report
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+If we expect our MARC file to contain only book records, we can easily locate and review records with other material types by using the `Find Records by Type` Report.
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Run Find Records by Type Report
+
+To run the Find Records by Type Reports
+
+1. Click Reports
+2. Select Material Type Report
+3. Select material type of records you want to review from the drop-down list. For this exercise select Continuing Resources.
+ A window will open displaying the Leader of each record. Double click on a result to be brought to that record in the MarcEditor.
+4. Click Close to exit the results window
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+The `Field Count` Report can also be used to profile your data. The Field Count Report lists each field found in your records, the number of times each field occurs in the record set, and the total number of records each field occurs in. While high level, the results can tell you about the cataloguing standards used (260 vs. 264) and identify potential errors (repeating non-repeatable fields), missing fields, local fields, etc.
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Run Field Count Report
+
+To run the Field Count Reports
+
+1. Click Reports
+2. Select Field Count
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+::::::::::::::::::::::::::::::::::::::: challenge
+
+## Locate errors using the Field Count Report
+
+1. What do the field count results tell us about our records?
+2. Looking at fields 100-300 do any of the results indicate errors in our records?
+
+::::::::::::::: solution
+
+## Solution
+
+1. Field count outlines each field found in our records, the number of times it occurs, and how many records it occurs in. Field count can also tell us the number of records in our file (536).
+2. Non-repeatable field 245 occurs more times than the number of records it's found in. At least one record contains multiple 245 fields. Field 245 appears in one less record than other required fields.
+
+
+
+:::::::::::::::::::::::::
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+### Edit functions
+
+Other useful tools for profiling your data can be found under the Edit tab.
+
+Like many applications, the MarcEditor provides a `Find` function. Find is particularly useful for locating and reviewing all instances of a MARC field within your data, or locating a particular text string within your data.
+
+We can use Find to locate and review the 245 field.
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Run Find Function
+
+To use the Find function
+
+1. Click Edit
+2. Select Find (*Ctrl+f will also launch the `Find` function)
+3. In the "Find what:" dialogue box enter =245
+4. Click Find All
+
+**Note:** When using `Find` to locate instances of a specific field, make sure to include the preceding = before the field number. Including the = ensures only matches on field number will be returned.
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+The Find results list is organized by record number, displaying the matched field content on the left, and the record number the field belongs to on the right. We can see from our results that Record # 8 appears twice, signaling that this record contains two 245 fields. By double clicking on "Jump to record #: 8" we could go directly to the record in our file to edit it. However, next we will show you a set of tools that can be used to locate and fix common errors like duplicate fields.
+
+The `Find Records With Duplicate Tags` function allows us to easily locate records with a duplicated field.
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Run Find Records With Duplicate Tags Function
+
+1. Click Edit
+2. Select Edit Shortcuts
+3. Select Field Edits
+4. Click Find Records With Duplicate Tags
+5. In the dialogue box enter 245 and click OK
+
+The results list includes two records with duplicate 245 fields, # 8 and # 28. Click on Jump to Record # to be taken to the record in the MarcEditor. Once on the record you can manually delete the incorrect 245 field.
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+The `Find Records Missing Field` function allows us to easily locate records with a missing field. To run this function
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Run Find Records Missing Field Function
+1. Click Edit
+2. Select Edit Shortcuts
+3. Select Field Edits
+4. Click Find Records Missing Field
+5. In the dialogue box enter 245 and click OK
+
+The results list will show one record missing a 245 field. Click on Jump to Record # to be taken to the record in the MarcEditor.
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+::::::::::::::::::::::::::::::::::::::: challenge
+
+## Correct the missing 245 field
+
+1. What's the issue with this record? Is the 245 formatted correctly?
+
+::::::::::::::: solution
+
+## Solution
+
+1. The 245 field number is formatted incorrectly. The MarcEditor relies on a standard format to identify and take actions on fields. Remove the rogue space and update the field number to correct this record.

+
+## Manipulating MARC data
+
+We've seen how we can manually and individually edit records in the MarcEditor, however, MarcEdit provides a number of more powerful ways to manipulate our MARC data. Fields, subfields, indicators can be added, removed, or changed. Fixed fields can be corrected. Fields and subfields specific to RDA can be added while AACR2 conventions are removed. It is possible to work with a subset of MARC data and then incorporate those changes into the original whole MARC data set. The variations sometime seem endless and give more weight to the nickname of MarcEdit, the swiss army knife of MARC data.
+
+### Find, Find All, and Replace
+
+Like many other applications, the MarcEditor offers the ability to Find, Find All, and Replace.
+
+Find: Find will search as a keyword what you enter into the Find window search box. This option will only search the current page in the MarcEdit. Remember that the default settings splits the MARC records into 100 for each page. Find will only search those records on the page you are currently on.
+
+Find All: Find all will search for your search terms entered in the Find window search box over all the pages, or all your MARC records.
+
+Replace: Replace works alongside Find or Find all. You have the option to Replace just those on the page or Replace all where the replace occurs on all pages in all records.
+
+If you want to Find or Find all a MARC field, you will need to include the equals sign before the MARC field. For example, if you type in the search box 856, Find or Find All will search for 856 as a keyword anywhere. If there is a title such as "The Jourey of the 856 people", this will then show up in your search results. If you search for =856, it will find anything with that string. If for example there is a title with "... =856 ..." then this will also appear in the search results. Typically the equals before the MARC tage will bring up that MARC tag.
+
+::::::::::::::::::::::::::::::::::::::::: checklist
+
+## Find, Find All, and Replace using the MARC field 856

+Remember to always verify that the search results of the Find or Find All. Find or Find all will search that exact phrase or string that you put into the search box either on that page (Find) or in every record (Find all).
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+### Add/Delete a MARC field
+
+To add or delete a MARC field, go to Tools in the upper menu in the MarcEditor and select Add/Delete Field. This will open a new Batch Editing Tools window. The Add/Delete Field functions are on the same menu level and you will need to select the action of either add or delete using the buttons on the right hand side.
+
+In the top middle section of the window, there are two data entry fields: Field and Field Data. Enter the MARC field number you want to add or delete in the Field dialogue box. Then enter the indicators, subfields, and data in Field Data dialogue box. Remember to include the dollar sign to indicate a subfield.
+
+{alt='MarcEdit empty Add/Delete Field dialog'}
+{alt='MarcEdit completed Add/Delete Field dialog'}
+
+To add the field, click the Add Field button and to delete any matching fields, click the Delete Field button.
+
+For both the Add Field and Delete Field functions there are a number of different options that can be applied to control the updates.
+
+The options to Add a Field include, if the field you are adding already exists, it can be inserted first in the list of those MARC fields or last. MARC fields can be added only if that MARC field is not already present in that record or based on the presence of other criteria found in other MARC fields. For example, a MARC field `655 \4$aElectronic books` can be added to only those records that are eBooks based on the data in the LDR or 008.
+
+The options to Delete a Field include removing duplicates, removing MARC fields based on field position, removing MARC fields that do not match what is entered in the Field Data, or removing invalid UTF-8 MARC fields. For example, to ensure that only the field `655 \4$aElectronic books`. is present in the MARC data, the option Remove if field data does not match can be selected.
+
+::::::::::::::::::::::::::::::::::::::: challenge
+
+## Add and then delete a MARC field

+### Add, Delete, or Change information for a subfield in a MARC field
+
+To edit subfield data within a given field, go to Tools and select Edit Subfield Data. A new Batch Editing Tools window will open (notice that this is the same window that opened for Add/Delete a field, you can also navigate between the MarcEdit Batch Editing Tools using the labels on the left hand side of the window). From here you can add a new subfield, delete a subfield, or replace text in a subfield. Set your desired subfield edit conditions by selecting the appropriate option(s) from the Search Options list.
+
+To add a subfield, enter the MARC field and then the subfield. The text you would like to add in that subfield is entered in Replace With box. Select New subfield only from the Search Options below and then click Replace Text. Even though you are adding a subfield, you still click Replace Text. For adding a subfield, the information that goes in that field doesn't go in the box called Field Data, see the example below.
+
+To delete a subfield, enter the MARC field and then the subfield. Select Delete Subfield from the Search Options and then click Remove Text.
+
+To replace text in a subfield, enter the MARC field, the subfield, the text (or information) that needs to be changed in the Field Data box. Enter your updated text in the Replace with box. Click on Replace Text.

+## Working with MARC fixed fields
+
+Working with fixed fields can be difficult. In the MarcEditor, you can edit one fixed field at a time using the easy editing window. If you put your cursor on that fixed field, such as an 008 or 006, then go to Edit and select Field 006 or Field 008. This will open up a window where you can edit the fixed field for that specific MARC record. To add one fixed field, put your cursor on the line where you want that fixed field inserted, go to Edit and then select Field 006 or 008. In the window, edit the fields for that specific record.
+
+{alt='MarcEdit fixed fields editor'}
+
+::::::::::::::::::::::::::::::::::::::::: callout
+
+## Batch Editing Fixed Fields in Multiple MARC Records
+
+Sometimes it is necessary to change a fixed field for all records in your MARC data. You can use the Edit Field function. For this, you will need to know the position of the fixed field. For this, you can consult the [OCLC Bibliographic Standards and Formats](https://www.oclc.org/bibformats/en.html) or [the Library of Congress Bibliographic Marc Standard](https://www.loc.gov/marc/bibliographic/). This is also possible using the Replace function and regular expressions which will be covered in Lesson 09.
+
+If you need to add a fixed field, you can use the Tools and select Add/Delete. You will need to have the 006 already formed. For example, you can add one 006 using the method explained above, copy that, and then use the Tools, Add field, to then add the 006. Remember that fixed fields don't have indicators.
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+## Saving, Compiling and Version Control
+
+The MARC data that you manipulate in the MarcEditor is in a human and computer readable mnemonic `.mrk` file format that was broken from the original binary `.mrc` file. You will notice that the file name of the file you're working on, displayed at top of the MarcEditor, has the file extension `.mrk`. If you look at the file in your file directory, the file icon color is blue whereas the binary `.mrc` MARC file icon is purple.
+
+### Saving
+When you save in the MarcEditor, you are saving your latest changes as a `.mrk` file. Using File → Save will save edits into your current `.mrk` file, overwriting the original. To keep a copy of your original `.mrk` data, select File → Save As and choose a new file name for your edited records.
+
+### Compiling
+To save your edited records back into a MARC binary `.mrc` file (the file format typically required to load MARC records in external systems such as your ILS or LSP) use the compile feature. Select File → Compile File into MARC. Choose a new file name for your edited `.mrc` file. Using the same file name as your original `.mrc` file will overwrite the unedited file.
+
+Records can also be compiled outside of the MarcEditor using the MarcMaker tool. To use the MarcMaker, from the Main Menu select MARC Tools. In the MARC Tools window, under Select Operation choose MarcMaker. Under Select Data to Process, in the Open box, select the `.mrk` file you'd like to compile. In the Save As box, specify the location and file name for your new `.mrc` file. Set the character encoding options as required, and then click Execute.

+## RDA Helper
+
+Records aren't created equal in that we encounter MARC data that follows different descriptive cataloging standards. There are a number of records cataloged according to the AACR2 standard or even AACR or earlier. Sometimes it is necessary to make sure these records follow the current RDA descriptive cataloging standard. MarcEdit lets you do this through the function called RDA Helper.
+
+To run the RDA Helper, go to Tools and select RDA Helper. In the window that opens, you can pick and choose how you would like to transform your records to align better with the RDA descriptive standard. For example, you can add the RDA fields 336, 337, and 338 for content, media, and carrier types. You can update the MARC field 040 to include the `$e` rda and delete the GMD statement. You can also evaluate the 260/264.

+
+Go to File and click on Select Records for Edit. In the window, you will see Display Field in the lower right hand corner. This is where you enter the MARC field you want to see displayed once you import your file. You can enter a MARC field and subfield or just a MARC field. The MARC field and/or subfield that you add in this box will provide the criteria you need to select records you want to edit. Once you have entered the Display Field, click on Import File. This will import the MARC (`.mrk`) file that you are currently working on. You can select another MARC (`.mrk`) file in the box Source MARC file.
+
+{alt='MarcEdit empty Select Records for Edit dialog'}

+- Successfully create and run a new task
+

+:::::::::::::::::::::::::::::::::::::::: questions
+
+- What are tasks?
+- How do you manage and create new tasks?
+- How do you run tasks?
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+## Tasks and Automation
+
+When working with MARC records regularly, you will likely encounter record sets where the data needs the same or very similar approach. A good example is electronic resource records where the resource URL in the 856 field will require the addition of an institution-specific proxy stem. Another example is adding RDA content, carrier, and media terms and codes to your records. Because MARC records typically need to meet cataloguing community standards and local best practices, it is necessary to manipulate MARC data to fit these standards and practices. In the previous lessons learned how to apply one change at a time. In this lesson, we will learn how to string together and automate these changes so they can be re-used in the future.
+
+In the MarcEditor, tasks are the tool that enable such automation. A task is a series of changes to MARC data that occur in the sequence they are entered in the task. One can think of tasks as a mini script of sorts that string together different MarcEditor functions that manipulate MARC data in some way. All tasks are created, managed, and run in the MarcEditor. In this way, tasks are another way to manipulate your data and are an extension of the other tools offered in the MarcEditor.
+
+## What are Tasks?
+
+A task is a series of MarcEdit functions to manipulate data. In the previous lessons, we ran one function at a time. Tasks string a set of functions together so you can run them as a group. Tasks run each function one after another. As such, it is important to think about how you order the functions in your task. For instance, if you want to add your institutions' proxy and the MARC data already has a proxy that you need to delete, your task has to account for that and remove the old proxy before adding a new one.
+
+Tasks are managed through the Task Manager in the MarcEditor. To access the Task Manager, go to Tools and then Manage Tasks in the top level menu. This will open the Task Manager window.
+
+In this window, you will see any tasks that you have created previously. You will see the name that you gave those tasks, the path to where those files are saved on your local computer, a shortcut, and a description. At the bottom of this window you will also have two options "Task Actions" and "Manage Existing Tasks".
+
+Task Actions include:
+
+- New Task: This will create a new task.
+- Clone: This will duplicate an existing task.
+- Delete: This will remove a task.
+- Edit: This will allow you to edit an existing task.
+- Rename: This will let you assign a different name to an existing task.
+
+Manage Existing Tasks include:
+
+- Assign to Group: This will let you put tasks into different categories or groups.
+- Assign keystrokes: This will let you assign shortcut keys to tasks.
+- Backup all tasks: This will let you backup your tasks to your local computer.
+- Delete Task Group: This is to remove an existing group.
+- Export Task File: This will save a selected task to your local computer for reuse or sharing.
+- Import Task File: This will bring in a task from your local computer.
+- New Task Group: This will allow you to create a new group.
+- Relink tasks: This will allow you to relink tasks.
+- Remove From Group: This will let you remove a task from a group.
+- Rename Group: This will allow you to rename a group.
+
+The difference between these two actions lists might seem confusing at first. Task Actions allow you to work with a particular task in terms of creating and managing one specific task at a time. The Manage Existing Tasks menu allows you to create and manage groups, exporting and importing, and assigning keyboard shortcuts to tasks.
+
+Tasks don't have to be categorized in groups or be linked to keyboard shortcuts. This is up to the users and their preference for how they organize their task workspace.
+
+## Create a New Task
+
+To create a task in the MarcEditor, Go to Tools in the top level menu and then Manage Tasks. In the Task Actions menu, select "New Task" from the dropdown menu and then click Select. In the dialogue box, enter the name of your task and click OK. This opens the Edit Task List window where you will see the name you gave your task, a description, tasks, and actions.
+
+Please note that though the Task List Name box allows you to change the name, these changes will not save. To change the name of a task, you need to go to Task Actions and select Rename task.
+
+You can add or update a description in this task list window. The box in the middle will list the functions (or tasks) for this particular task. If there are none, this window will be empty.
+
+Actions include:
+
+- Add: Add a new function or task
+- Copy: Clone a function or task already in the list
+- Delete: Delete a function or task
+- Edit: Change an existing function or task
+
+You can add a new task by clicking on the plus button. You can add any type of function available in the MarcEditor Tools and Edit Shortcuts menu options. This includes the RDA Helper, build a new field, change the case of a MARC field, or generate cutters. You can even include a list of functions (tasks) from another Task.
+
+Click on save at the left bottom corner of the Task List window to save your Task. From there you can close the Task Manager window. To run a task, go to Tools → Assigned Tasks → Current Tasks.
+
+If you have created many Tasks, it does help to assign them to groups to more easily find what you need. If you don't use Groups, the Task Manager will list all of your Tasks in alphabetical order and it might be difficult to see them, especially on small screens such as laptops.

+To edit an existing task, go to Tools → Manage Tasks. In the Task Manger select the task you want to edit, this will highlight the task. Under Task Actions choose Edit Task and click Select. This will open the Edit Task List window. Just like when creating a new task, you can add, delete, or edit functions in your task. Use the up and down arrows to the right to reorder your functions.
+
+::::::::::::::::::::::::::::::::::::::: challenge
+
+## Add a proxy to the `856 40$u` in your Task
+
+1. After you run your Task, your MARC records should have your institution's proxy before the URL. Remember to check your data first to see if there are any proxy stems present. You will need to remove any existing proxies before running your Task. If the MARC data has different types of electronic URLs (resource, related resource, etc.) as noted in the MARC field 856 indicators, you will need to account for that in your Task.
+

+## Solution
+
+1. Go to Tools in the upper menu in the MarcEditor
+2. Select Manage Tasks
+3. Select the Task you just created. The selected Task will be highlighted.
+4. In Task Actions, select Edit Task and click Select.
+5. Select the plus button and select "Add a Replace All Task"
+6. Replace the `856 40$u` with `856 40$u[your proxy]`. Remember to add 2 spaces after the MARC field.

+## Copying Functions to Tasks
+
+It's possible to copy many functions run in the MarcEditor to a Task for easy reuse. To copy a function, look for the "Copy Task" button in the Batch Editing Tools and Replace Text windows. By clicking "Copy Task" after you've designed and run a function successfully, you can save that function. To add the function to a Task, go to Tools → Manage Tasks. In the Task Manger, under Task Actions choose New Task and click Select. Once in the Edit Task List window, right click and select "Paste Task Action". You can also add the function to an existing Task by selecting Edit Task, instead of New Task.

+## Integrations
+
+MarcEdit has the ability to interface (or integrate) with other applications. Integrations with other cataloguing utilities, such as vendor ILS and LSP systems and OCLC WorldCat, support advanced actions which can include downloading records, pushing new records or record updates, and setting holdings (OCLC WorldCat). Currently, MarcEdit can integrate with the ILS Alma, Koha, or a local ILS if you are able to connect to the host database. MarcEdit can be set up to integrate with OCLC's APIs for metadata and connect to OCLC or the Library of Congress (either UTF-8 or MARC8) Z39.50 services.
+
+For the ILS integrations you will need one or some of the following:
+
+- Host URL of the database
+- Username and password
+- Token
+
+If you are setting up an integration to your ILS, it is recommended to touch base with those who have already done this. For example, for Alma, you can reach out to the Alma listserv to get guidance.
+
+For the OCLC API integration, you will need to request an API key with OCLC. You will need the Registry API, Metadata API, and Search API. It is recommended to consult OCLC's help page on [setting up MarcEdit OCLC integration](https://help.oclc.org/Librarian_Toolbox/OCLC_APIs/Troubleshooting/How_do_I_set_up_MarcEdit_OCLC_Integration%3F?sl=en) as well as Terry Reese's information from his blog.
+
+For the Z39.50 integration, you will need to enter your username and password in the settings. For OCLC, this is your Connexion number and password. For the Z39.50 search for OCLC, there are options for the types of searches performed and translating records to UTF-8.

+- What are regular expressions?
+- Where and how can you use regular expressions in the MarcEditor?
+- What types of edits can you accomplish with regular expressions?
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+
+
+## Regular Expressions
+
+Regular expressions, often referred to as regex, are a tool you can use to match, capture and manipulate data across your MARC record file. Regular expressions are comprised of a sequence of literal characters and metacharacters which are formulated to match a particular pattern found in your data that you want to manipulate. A detailed introduction to working with regular expressions can be found in the [Library Carpentry lesson Introduction to Working with Data (Regular Expressions)](https://librarycarpentry.org/lc-data-intro/index.html). In this lesson we will focus on the application of regex in the MarcEditor.
+
+## Regular Expressions in MarcEdit
+
+MarcEdit uses the .NET regular expression syntax. Visit the .Net [Regular Expression Language - Quick Reference](https://docs.microsoft.com/en-us/dotnet/standard/base-types/regular-expression-language-quick-reference) for a breakdown of the syntax used for regex metacharacters in MarcEdit. You can also download the [.Net Regex metacharacter reference sheet](https://download.microsoft.com/download/D/2/4/D240EBF6-A9BA-4E4F-A63F-AEB6DA0B921C/Regular%20expressions%20quick%20reference.pdf) to support the creation of your own regular expressions in MarcEdit.
+
+Many MarcEdit functions support the use of regular expressions for data selection and manipulation. They include: Find and Replace, Edit Field, Copy Field, Swap Field, Build New Field, Delete Field, Record Validation, and both the Extract and Delete Selected Records tool. The intent of this lesson is to demonstrate where and how you can leverage regular expressions to work with your MARC data.
+
+## Edit Field Data
+
+With regular expressions you can easily locate variations in your data and replace them with a single value. In our file the OCLC identifier in the 035 field uses the prefixes `on`, `ocn`, and `ocm`, but our library formats the OCLC with the `(OCoLC)` prefix. Instead of running three Edit Field Data functions to update these prefixes, we can use a regular expression in the Edit Field Data tool to replace these prefixes with the `(OCoLC)` prefix in a single edit.
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Update 035 OCLC prefixes
+
+1. Select Tools → Edit Field Data
+2. Enter the following values:
+ Field: `035` Find: `on|ocn|ocm` Replace: `(OCoLC)`
+3. Check Use Regular Expressions box
+4. Click drop down menu → Preview Results
+5. Verify your results look as expected, close preview tab and then click Process
+ In this regular expression we use the pipe (`|`) metacharacter to specify that we are looking for the string `on` OR `ocn` OR `ocm`. We then replace the captured string with `(OCoLC)`.
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+::::::::::::::::::::::::::::::::::::::::: callout
+
+## Knowing your dataset
+
+Regular expressions are a powerful tool, but using them can sometimes lead to unexpected and undesirable results if you do not know your dataset. In the Edit Field Data exercise above, any 035 field containing the string `on`, `ocn`, or `ocm` would have had these values replaced with `(OCoLC)`.
+
+For example: `=035 \\$a(SFUonline)638023` would have become `=035 \\$a(SFU(OCoLC)line)638023`
+
+Reviewing your dataset before employing regular expressions is a good best practice. The MarcEditor Preview Results feature also supports trial and error.
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+## Find and Replace
+
+The Find and Replace tool is another useful way to identify and manipulate data in the MarcEditor with the support of regular expressions. In our file the local call numbers in the `090` field are formatted without a space between the class and subclass (ex. `LD1780` and not `LD 1780`). To update the call number to follow our local policy we need to isolate the components of the call number so we can add a space between them. We can do this with a regular expression by employing groups.
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Add a space between 090 class and subclass
+
+1. Select Edit → Find
+2. Enter `=090` in the Find box and click Find All
+ Review the list of `090` fields, what observations can you make about the call numbers in this field?
+ Review shows us that not all call numbers begin with letters. We do not want to add a space to these call numbers and need to account for this in our regular expression.
+3. In the Find window, click Replace to bring up the Replace Text functions
+4. In the Find box enter the regular expression `(=090 \\\\\$a[A-Z]+)(\d.*)`
+ This regular expression uses two sets of `()` to capture groups and then manipulate them.
+
+- Broken down, the first group `(=090 \\\\\$a[A-Z]+)` will match the literal string `=090 \\$a` (the additional backslashes are used to escape the regex metacharacters `\` and `$` so that they will be read as literals) followed by any single capital letter in the range A to Z (`[A-Z]`) one or more times (`+`). By specifying that the regular expression must locate a capital letter at the start of the call number, the regular expression will not edit the call numbers that begin with a digit.
+- The second group `(\d.*)` will match any digit (`\d`) followed by any character (`.`) zero or more times (`*`)
+
+5. In the Replace box enter `$1 $2`
+ This regular expression refers back to the groups we defined and captured in the Find box. `$1` refers to the group defined in the first set of brackets, and `$2` refers to the group defined in the second set of brackets. If we had defined additional groups they would be referred to chronologically as `$3`, `$4` etc. The regular expression `$1 $2` will output the contents of the two captured groups with a space between them.
+6. Check the Use regular expressions box
+7. Click drop down menu → Preview Results
+8. Verify your results look as expected, close preview tab and then click Process
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+## Select Records for Edit
+
+The Select Records for Edit tool, introduced in lesson 6, allows you to isolate and then work with a subset of your records. Regular expressions can be a powerful tool to help you isolate the subset of records you want to work with.
+
+In this example we want to add the electronic journals genre form (`655 \\4$aElectronic journals`) to our electronic continuing resource records.
+
+Working with fixed fields, where character position and coded values impart specific meaning, can be difficult for the human eye. However, regular expressions make it easy to specify the position of a character in a text string in order to find, select or update that data.
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Isolate continuing resource records
+
+1. From the top level menu select File → Select Records for Edit
+2. The file you are working on will be selected by default in the Source MARC file box. To import the Leader for review, enter LDR in the Display Field Box and Click Import.
+3. To isolate continuing resource records we find any records where `LDR/07` = `i` or `s`. In the Find box, enter the regular expression `.{7}[is].{16}`
+
+- This regular expression looks for any 7 characters (`.{7}`)(Leader positions 0-6), followed by the character `i` OR `s` (`[is]`) (Leader position 7), followed by any 16 characters (`.{16}`)(Leader positions 8-23)
+
+4. Check the Use Regular Expressions box and then click the magnifying glass. A popup window will let you know how many records were selected based on your criteria.
+5. Click Export Selected. You will get a popup will let you know the records have been extracted. Click OK.
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+::::::::::::::::::::::::::::::::::::::::: callout
+
+## Inverting your selection
+
+When using the Select Records for Edit tool you can use the Invert Selections option to select all records that DID NOT meet your criteria. This option can be helpful when you want to select all records except for those that meet a specific criteria.
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+::::::::::::::::::::::::::::::::::::::: checklist
+
+## Edit selected records
+
+Now that we've isolated our continuing resource records, we can add a field for the electronic journals genre form (`655 \4$aElectronic journals`) to the electronic records in our subset.
+
+1. From the top level menu select Tools → Add/Delete Fields
+2. In the Batch Editing window, enter 655 in the Field box and enter `\4$aElectronic journals` in the Field Data Box. Under General Options select Use Regular Expression, and under Add Field Options select Add Field If Present/NOT Present.
+3. To add our 655 field to electronic records only, we need to specify what should be present in the record for the new field to be added.
+ What are some fields and values we might look at to determine format?
+ For this example we are going to use a regular expression to look for the presence of an 856 link or a the carrier type online resource. Enter the regular expression `=856|=338.+online resource` in the Find What box.
+
+- This regular expression looks for the string `=856` OR the string `=338` followed by any character (`.`) one or more times (`+`), followed by the string online resource
+
+4. Click Add Field. Review your data, were the new fields added correctly?
+
+
+::::::::::::::::::::::::::::::::::::::::::::::::::
+
+After editing your subset of records, you can either save the edits back into the original file, or save the subset of records to a new file.
+
+To save the edits back into the original file, select File → Save (Ctrl+S). You will get a dialogue box indicating that your records have been saved back into the original file.
+
+To save your subset of records separately, select File → Save As. Specify the name and location of your new file and click Ok.
