WorldCat
Official destination: https://search.worldcat.org/
WorldCat combines catalog records from thousands of libraries so users can search for books, articles, maps, recordings, scores, images, and other physical or electronic materials. Records can identify libraries that report owning an item.
Why it is useful
WorldCat is particularly helpful for material that does not appear in an ordinary web search or is available only through a library. It can provide the information needed to ask about an interlibrary loan.
Best for
Locating books, media, archives, and other materials held by libraries
Not ideal for
Immediate online access to every item in its catalog
Limitations
A WorldCat record does not guarantee that an item is digitized, currently available, or accessible without a library account. Availability and borrowing rules depend on participating libraries.
