For genealogists, WorldCat has many uses. Researchers can search library holdings by title, subject, and author; locate the nearest repository where an item is housed; identify items to order through interlibrary loan; and assist in finding items available online. WorldCat is also a good place to find citations for materials used in documenting sources. WorldCat is now being expanded to catalog content on the Web, increasing the visibility of materials such as the historical photos and archival documents found in various museums and archives.
