TIP OF THE WEEK –
MAPS ONLINE AT LIBRARY OF CONGRESS
This question came up on the SGS Networking Group Facebook page, “Is there an online map of Seattle as it would have looked in the 1940 census?” Normally a King County resident would go to the downtown Seattle Public Library and search the Sanborn Fire Insurance Maps, but with SPL closed, what is a person to do? 

Group member, Darren, advised that while Seattle Public Library has an extensive map collection, they do not have much online. He suggested checking for Sanborn maps  online at  the Library of Congress website.  Great, they had maps of Seattle, King County, WA for years pretty close to 1940. 

Whether you want an old Sanborn map for Portland, Cumberland County, ME or Portland, Multnomah County, OR, you may be able to find it with a simple online search at :
