WorldCat is the OCLC Online Union Catalog. It contains millions of records of items owned by libraries around the world. Every item in the catalog has a listing of libraries which own it. It contains records for books, journals, musical scores, electronic resources, and much more. It does not include records for individual articles in journals, magazines, newspapers or book chapters.
While Worldcat will provide you with an overview of libraries owning a given book, it will not provide information as to its availability. You will still need to check the holding library's catalog to see if the book is available, is for library use only, or is currently charged out.
A link to WorldCat is available throughout our site in the side navigation bar.
