ISBNiser and ISBNquest Version 2.1 Released

I have just posted version 2.1 of the ISBNiser utility and ISBNquest Web resource. These are utilities which validate, inter-convert, and properly format all varieties of International Standard Book Number (ISBN) specifications. Both utilities have been updated to use the most recent version of the ISBN Range database (Wed, 6 May 2020 14:51:46 CEST), replacing the October 2018 version previously used. The range database is used to parse ISBNs into their components (Prefix, Registration group, Registrant, Publication, and Checksum) and used by these tools to re-format ISBNs with the correct punctuation.

ISBNquest has been updated to use the new Amazon Product Advertising API 5.0 to look up books on Amazon and find title, author, and other information for a book from its ISBN. This replaces the 4.0 version of the API which has been retired and no longer works. The mechanism used to locate Kindle editions of print books has been completely redesigned and should now work for many more (but, due to limitations in the API, not all) books.

There are no user interface changes in either of these utilities, and updating to them should be completely transparent for all human and programmatic queries.
