About WorldCat.org
Introduction to WorldCat.org
WorldCat is the world's most comprehensive database of information about library collections. Unique in scale and unparalleled in data quality, WorldCat makes library collections findable and accessible around the world. It's where you can locate a book, video, or other items of interest and discover which libraries near you own the item. Individual member libraries in your community and elsewhere provide access to the items represented in WorldCat.
