Here's a link to some old books. I've found some really neat stuff - love the old cookbooks
Genealogy Book Links
This is a great online tool! Mollie Lynch of Clarkston, Michigan, is a retired librarian who decided to assist people wishing to find genealogy books. She knew that thousands of American biographies, genealogies and history books have been digitized and made available on the Internet, usually free of charge. However, there was no single resource of "what is available and where." Mollie decided to create that resource.
GenealogyBookLinks.com focuses solely on American biographies, genealogies, and history books. However, as the years go by, I expect that we will see similar resources for thousands of other topics, thereby creating true digital libraries of books of all topics.
