Sanborn Maps From Google and Historic Sanborn Maps from Many Providers (Free and Fee)
News from GB that they are making available a new set of maps on the Google Maps site labeled "terrain."
Cool? You bet.
Here's mid-town Manhattan. Info pros will quickly realize even before looking at the bottom of each map that what they are looking at are Sanborn maps.
In other cases (no Sanborn map), users are looking at terrain/physical maps, similar (but not exactly the same) as to what the USGS offers (at no charge) from many databases. Many might call them physical maps*** vs. topographic maps.
Here's an example, at Level 1 where you can see some Sanborn content and other areas where it's not available.
Sanborn fire insurance maps are the most frequently consulted maps in both public and academic libraries. Sanborn maps are valuable historical tools for urban specialists, social historians, architects, geographers, genealogists, local historians, planners, environmentalists and anyone who wants to learn about the history, growth, and development of American cities, towns, and neighborhoods. They are large-scale plans containing data that can be used to estimate the potential risk for urban structures. This includes information such as the outline of each building, the size, shape and construction materials, heights, and function of structures, location of windows and doors. The maps also give street names, street and sidewalk widths, property boundaries, building use, and house and block numbers. Seven or eight different editions represent some areas.
Now, are there any Sanborn Maps available on the web from sources other than Google, especially historic maps?
The answer is yes.
Here are a few of MANY sources with MORE to come. Access to these collections is completely free.
A collection of more than 3,000 map sheets digitized from the printed maps held in the collections of the Smathers Libraries' Map & Imagery Library, at the University of Florida.
The Sanborn Map Collection consists of a uniform series of large-scale detailed maps, dating from 1867 through 1969 and depicting the commercial, industrial, and residential sections of cities.

Fee-Based Sanborn has been providing these and many other types of maps since the mid 19th century. A database of digitized historical Sanborn maps (1867-1970) is a fee-based service from ProQuestCSA. Over 660,000 maps are available for more than 12,000 U.S. cities. NOTE: MANY libraries provide remote access to this database at no charge.

The goal was to put 1 million historic maps online. From the page:
On June 13, 2000, the Library of Congress terminated its cooperative agreement with EDR Sanborn. The Library of Congress and EDR Sanborn could not come to agreement regarding issues of access and copyright notice for the digital files of the Sanborn Fire Insurance maps.
