Sanborn Maps as a resource
It turns out that Princeton U's Library has posted a pretty significant collection of Sanborn Fire Insurance maps.
While the collection of New Jersey maps is fairly extensive, it isn't all scanned yet. The key to using this for much of New Jersey is that you have to first download their excel spreadsheet and click on the link for the appropriate set of Sanborn maps.
I've posted my photos of Sanborn maps from the Library of Congress map vault. The top photo shows some red brick buildings near the blue stone construction of Ebbets Field in Brooklyn. You can even see that the area behind home plate was brick construction, which shows in some of the photos. The maps are great because they are so detailed and help track change over time.
