I believe one of the least used resources for genealogy research is the local library. No, it may not have books, microfilms, or documents that will help you. However, most of them have computers.
Yes, I know. We have computers at home. But did you know that most of them have subscriptions to ancestry.com? And it’s FREE!! For use in the library. Some libraries even have subscriptions to obituaries, footnote and other sites. And don't forget Heritage Quest.
Also, don’t forget the local Family History Centers. Because they are staffed by volunteers, the hours vary. These FHCs often have ancestry.com as well as other subscription sites. Some of them have 5 or 6 different sites. You can use the computers for free and check out the options. Then, either continue to use this valuable resource, or decide to pay for one or two so that you can stay at home. But this is a great way to learn about more and different online resources.
