Here is this weeks challenge, written by Amy Coffin (www.wetree.blogspot.com) and posted, along with other bloggers posts on the subject, at www.geneabloggers.com
DISCOVER ONLINE MAP COLLECTIONS. Historical maps are wonderful tools for historical research. Fortunately for genealogists, many map collections are located online. Some of the more prominent collections are: the American Memory Collection at the Library of Congress, the David Rumsey Map Collection, and the Perry-Castañeda Library Map Collection at the University of Texas at Austin. Take some time to browse each of these collections. You may also want to check the library web site of your local university (or one near your ancestral home) to see what maps they may have online. If you have a genealogy blog, write about any special maps you find during this activity.
This challenge runs from Saturday, 20 February 2010 through Friday, 26 February 2010
