I have written a Perl script to decode the Cuecat output so I could capture ISBNs and catalog my book collection. Several sites host Web services that return book information given the ISBN. Below is a GET request that requests the title of The 2007 ARRL Repeater Directory.

By modifying the last variable in the URL, specifically the value after “fl=”, the publication date or author can be retrieved. See examples below:
