Do you use our subscription databases from home? If so, you'll be interested in MyHeritage Library Edition. Sign in with your library card to see images of U.S. census records 1790–1940, U.K. census records 1841–1901, user contributed family trees, and many other references, guides, and directories.
Another genealogy database, HeritageQuest, was recently enhanced with expanded census images and name indexes, an all-new image viewer, and over 40,000 books and city directories. Part of the Tennessee Electronic Library, HeritageQuest does not require a library card number but you must use it on a computer network recognized as being within Tennessee.
