WorldCat is a catalog of most libraries in the U.S. & Canada and many from other countries. Find books, DVDs, web sites, musical scores, archival material and more.
There are two versions of WorldCat, the subscription version from First Search, which is below and which I recommend, and the free version. If you find something you need while searching in WorldCat, and we don't own it, we can usually get it from another library. See InterLibrary Loan (ILL) to learn more. One great feature of the First Search version is that it automatically fills out your ILL request form.
