You may be able to get FREE access to ancestry.com until the end of September (at least). Even for those not interested in genealogy, it can provide a few hours of entertainment during the long summer days, looking for where your ancestors were decades ago.
Many libraries subscribe to the Library Edition of Ancestry, which you can use for free if you're sitting in the library, and now they've made it accessible remotely to anyone with a library card. You need to first check if your local library has it, and then you'll need to enter the serial number of your library card to use it.
The Library Edition has passenger lists of immigrants, census records until 1940, phone and address directories, military records, school yearbooks, and more. The Library Edition does NOT include the ability to post your personal family tree.
