The Ancestry Library Edition collection has approximately 4,000 databases including key collections such as U.S. federal census images and indexes from 1790 to 1930; the Map Center containing more than 1,000 historical maps; American Genealogical Biographical Index (over 200 volumes), Daughters of the American Revolution Lineage (over 150 volumes), The Great Migration Begins: Immigrants to New England, 1620-1630, Social Security Death Index, WWI Draft Registration Cards, Federal Slave Narratives, and a strong Civil War collection. All materials may be searched at once (using a basic or advanced search screen), or various databases and indexes may be searched individually.
You may access Heritage Quest at home through your public library GALILEO account. Heritage Quest offers access to portions of the census and other traditional genealogy records plus the PERSI database (periodicals index) and full text published genealogies.
Another resource you may not have thought of using is Lexis Nexis to begin "leafing out" your family tree. Lexis Nexis offers a People search using 22 different resources from the New York Times - Biographical Materials to the Martindale-Hubbell Law Directory.
The key is to start with yourself and work back - one generation at a time!
You may get the password to use GALILEO at home from your Georgia librarian. Remember your public library GALILEO offers slightly different resources than the academic GALILEO!
