Title: Added support for Harvard's non-standard 690-5 field

The 690-5 field describes the individual Harvard Library that holds the work. See [the documentation](http://openmetadata.lib.harvard.edu/sites/default/files/Harvard_Library_Bibliographic_Dataset_Documentation.pdf) for specifics.

Also added logic to ensure duplicates entries are removed, which is especially common with the 690-5 field.
