Woo hoo! You can now search WorldCat directly, without an account, and find out what libraries anywhere carry the book / CD / DVD / etc. that you want!
See the box to the left of this post? Try it out!
Note: this will *not* work if your library hasn’t put its holdings into OCLC. Long story, for library geeks only.
Found this through the OCLC It’s All Good blog.
