Implementation notes, if any

• Investigate using citeproc-ruby

I tried citeproc-ruby and ran into some problems.
a) I could not figure out why, but when using the MLA format, it did not add the delimiter between the last and first names. This could be a bug or driver error?
b) The publisher is not in the Solr record without the place of publication, which is needed for most MLA book citations.
c) Again, this could be my own error, but I can't get all the fields I need without another call to Solr. At that point in the code, the fields included in the document are very minimal, and the semantic values, which should include the citations fields, do not seem to at this point. I don't know if this is a loading order issue or what?

The .ris extension does work for SCSB items.
