Hello all,

Thank you to everyone who replied to my request for links to your online fire insurance maps. Many institutions have their maps online with excellent finding aids. Many libraries provide online access via the ProQuest database. The best single place for online Sanborn maps is the Library of Congress.

I created a quick libguide with the information I gathered. It is a work in progress but includes all the information shared with me via my Maps-L inquiry.

Feel free to offer suggestions, updates, comments.

Thank you again for your help.
