Very useful to find library materials and to help building up a bibliography.

Content seemed accurate, objective, and reasonably well researched. I didn't need more than that.

Very good site, used by many libraries for database purposes.

Catalogue of library.

One of the most awesome places to find resources, books and materials! Not only can you find almost any book, it will cite the book, and tell you where you can find it in your area. Awesome and safe to use from my experiences!

Good information.

WorldCat is a useful place to search for materials in a library near you. It is a global catalog of library collections. Safe and useful site.
