1. Want a copy of a webpage for your files or to attach to your family tree? Use this (free) site to convert a webpage to a .pdf http://pdfmyurl.com/ .
2. Check out the (free) Chronicling America collection at the Library of Congress website http://chroniclingamerica.loc.gov/. Here you will find (indexed) images of newspapers, 1860-1920, for Arizona, California, District of Columbia, Florida, Hawaii, Illinois, Kansas, Kentucky, Minnesota, Missouri, Nebraska, New York, Ohio, Oklahoma, Oregon, Pennsylvania, Texas, Utah, Virginia and Washington state.
3. http://babelfish.yahoo.com/ is a site I use when I need to translate a couple of words or sentences from or to another language (it has only the most common languages, for example, no Lithuanian).
I find this helpful when translating documents (such as those found in the French Canadian, Drouin Collection) or when letter writing to foreign repositories.
There is also a section that allows you to enter a URL and it will translate the entire page for you.
4. For those of you with Boston ancestors, this is an interesting site, illustrating how stories may be woven from city directories (it also includes free access to a number of digitized Boston street directories 1845, 1855, 1865, 1870, 1872, 19875, 1885, 1905, and 1925) http://dca.lib.tufts.edu/features/bostonstreets/index.html fun to check out even if there are no Bostonian’s in your past.
5. Although Google is (in my opinion) the top search engine, be sure to search for your ancestor’s using other search engines as their algorithms (hence results) may differ: http://en.wikipedia.org/wiki/List_of_search_engines
6. Almost all researchers know of the Family History Library, but did you know that the Allen County Public Library has the 2nd largest collection of genealogical records in the USA? http://www.acpl.lib.in.us/genealogy/index.html
7. When searching in Google, the ~ tilde character finds up to 10 synonyms and related words. For example, including ~genealogy (no space) in your surname search will reveal results which include such terms as family tree, ancestors, etc. Stop by the library and pick up a copy of “Google Your Family Tree, Unlock the Hidden Power of Google for Genealogy & Family History” by Daniel M. Lynch for more tips – http://www.googleyourfamilytree.com/
8. As an aid in finding where your ancestor may be buried or which church they many have attended (assuming it still exists), I add the street/city (from the census or city directory) and then use mapquest or google maps with the word cemetery or church to get a listing of those closest their ancestral homes.
9. Use the following website to view a variety of demographics collected in the census years (1790-1960) and “map it” either for the whole country or for particular counties in a state: http://mapserver.lib.virginia.edu
