Version 1.0.59 - 2023-04-06
The LCCN Identifier values are
automatically converted to remove each value's prefix of "lccn-' so that they may be used as-is with the URL to the Library of Congress Permalinks to the book's author. Example: Identifier Type "lccn" value "lccn-n80126289" will be converted automatically to "n80126289".
The format for one possible Permalink is:
https://lccn.loc.gov/n80126289 where the n80126289 is the LCCN value from Library Codes.
Another Permalink is:
https://id.loc.gov/authorities/names/n80126289.html
You may set either of these links in Calibre > Preferences > Look & Feel > Book Details.
LCEAD, Library Codes Extra Author Details, is permanently deprecated in LC and will not be available in the future.
A superior, dynamic replacement for LCEAD that does not have to be downloaded from Worldcat.org is the second Permalink shown above:
https://id.loc.gov/authorities/names/n80126289.html where n80126289 is the LCCN.
See the attached example for Isaac Asimov. Note the LCCN of n80126289 in the URI.
Another change: If a book has
both an ISBN
and a OCLC-WI that you downloaded using the Author/Title menu option, LC will now use the OCLC-WI instead of the ISBN in the "routine" menu option, ISBN/ISSN/OCLC-WI. That is because you don't need to download the OCLC-WI unless the ISBN is not working for you.
Remember to click the LC icon's down-arrow in the Calibre ToolBar in order to see all of the options of LC. Just clicking the LC icon to get the "default" is great if ISBN works; otherwise, you have to get the OCLC-WI via Author/Title.
