A while ago the Allen County Library launched a new website designed with the purpose of aiding family research without having to actually visit the library.
The home page gives you links to tips on getting started in genealogy as well as forms to search their free databases and their catalog.
A particularly interesting exploration is the "Pathfinders" tab at the top of the home page. It will lead you to pages that can guide you in conducting research in several differed areas such as adoption, German, Irish and more.
You can find the site at http://www.genealogycenter.org/Home.aspx
Thanks to Dick Eastman for mentioning this site in his online newsletter.
