There has been a lot of information out there about WorldCat and to be honest I can’t keep it all straight.  So here is my reading list:

• The splash page for the WorldCat API
• WorldCat’s Developer network houses the WorldCat API Documentation
• David Walker did a presentation on the WorldCat API at Code4Lib 2008
• The World Cat Developers’ Network Blog…just in case
• Karen Coombs, author of the blog Library Web Chic, has a number of postings on the WorldCat API

If you figure out how to download the information into my brain let me know.
