[GUI Plugin] Library Codes


Functions and Features:

[1] Automatically creates new Custom Columns (if desired) for Dewey Decimal Code and/or Library of Congress Code and/or OCLC-OWI and/or FAST Tags.

[2] Derives the desired Library Codes using a book's ISBN or ISSN [Selected Books].

[3] Optionally creates Identifiers: OCLC-OWI; OCLC-WORLDCAT; and VIAF_AUTHOR_ID. This allows the use of composite Custom Columns to be shown in the Book Details as a hot-link to the respective URLs.

[4] Optionally Converts ISBN-10 to ISBN-13 [Selected Books]. This function will also automatically "sanitize" ISBNs to remove any dashes, etc. even if the ISBN is already an ISBN-13.

[5] Optionally extracts ISSNs from PDFs for Magazines and Periodicals. The other LC functionality then may be executed for the PDFs for which ISSNs were extracted. View the LC Menu ToolTips for more information.

[6] Optionally maps either a LCC or a DDC for each book to a 'Genre', and updates a Text custom column with that mapping. LC comes preloaded for DDC mappings, but a template .csv file for LCC mappings is attached below.

Please read the ToolTips in the LC customization settings.
