In our continued quest to give our members the best data possible, we’ve added 417 new cataloging sources from around the world to LibraryThing.

It’s a lot to take in at once. We’ve added or greatly increased our support in a number of areas; here are some of the highlights:

That’s a pretty good mix, but the vast majority we added were US or Canadian libraries, even though we already had plenty of both. We’re still pretty weak in some areas, and completely missing in others. We use a protocol called Z39.50 to get book data from libraries. Quite simply, these are all the Z39.50 servers we could find info for and could get working with our software. We’d love to have thousands more, from all corners of the globe. Any library that has a Z39.50 server that would like to be on LibraryThing just needs to send me their connection info and I will add them.

All of these have been tested fairly thoroughly, but I’m sure there will be problems with some of them. Z39.50 is fickle and complex, and the servers are often unreliable. So some problems may be caused by misconfiguration on our part, and some may be due to circumstances and servers we can’t control. Let us know when there are problems, and we’ll do what we can.
