Help, Guides and Instructions: WorldCat

This Research Guide helps patrons of the NWC Library make the most of their library experience by introducing important databases and resources available to them. It serves as a starting place to learn how to use the library online catalog and databases.

How to Search WorldCat

WorldCat (World Catalog) is an online catalog of books and other materials such as manuscripts, documents, audio-visual materials, musical scores, and sound recordings in libraries worldwide. It is the world’s largest online catalog. Updated daily, it includes more than 1.5 billion records for items representing 400 languages. Search WorldCat to identify books and other materials that are not found in the NWC Online Catalog.

If you wish to obtain an item in WorldCat that is not held by the NWC Library, you may request an InterLibrary loan for that item by completing the online form on the NWC Library’s home page.
