Your Virtual Library Card
Working the Web? Discover what Yahoo! misses—the family history riches of libraries around the world. Here's how to plug into online library catalogs.

Once you've combed the Web for your family history with Yahoo!, AltaVista, Excite or another search site, you might think you've found all there is to find. But you'd be missing some of the most useful family history resources on the Internet: the online catalogs of your old offline friend, the library.

Web researchers might mistakenly assume that Internet search engines index items listed in online library catalogs. In fact, you must search each online catalog directly to identify specific items held by the library that might hold answers to your genealogical mysteries.

Just like the old card catalogs in wooden file drawers, library catalogs on the Internet help you find books and other materials in a library. Now that many libraries have placed their catalogs online, you can easily find out what family history resources are available in libraries across the US and even in other countries.

Here are some of the most important online library catalogs for family history researchers. For more links to library catalogs of state libraries and historical societies, national libraries and libraries with important ethnic collections, as well as directories of library Web sites and online catalogs, see our library links.

For detailed writeups on these sites and tips on making the most of "Your Virtual Library Card," see the April 2000 issue of Family Tree Magazine.
