Ever hear of WorldCat? Until recently, this OCLC product was known primarily to librarians and used mostly by catalogers. Recently, however, access to WorldCat's holdings--more than 82 million records held by some 56,000 libraries--has been opened up to anyone with a web browser.
If you want to try your hand at WorldCat searching, a link can be found on the Waterloo Public Library website under the "Resources" tab.
