I'm sure many of you are already familiar with OCLC's xISBN service. Today I released "thingISBN," LibraryThing's "answer" to xISBN. Where xISBN uses OCLC's FRBRized data, thingISBN uses LibraryThing's "everyone a librarian" wiki-like cataloging. The results are pretty interesting, I think. xISBN has better coverage and I suspect makes fewer mistakes, but thingISBN is strong on paperbacks and non-US editions. There's a way of asking it to compare the two, so you can evaluate it yourself. Like xISBN, it's free for non-commercial use. It follows the xISBN XML format, so it can be plugged into existing code quite easily. I'm interested to see if anyone does anything interesting with it. I blog about the service here http://www.librarything.com/thingology/2006/06/introducing-thingisbn_14.php Comments, of course, appreciated. And for what it's worth I'm still looking for a crackerjack library programmer... Tim LibraryThing.com
