COVERAGE

Microfilm reproduction of fire insurance maps produced by Sanborn Map Company, 1916-1980 covering Philadelphia county, Pennsylvania. The two microfilm sets represent building outlines and hydrant access for structures in Philadelphia through several revisions of Sanborn maps. The original maps also indicate building construction materials through coloration. The original maps were drawn at 1:600 or 1":500' scale.

The Chadwyck-Healey set, reproduced from originals held at Library of Congress, consists of two complete sets of Sanborn maps, each completely covering the city in 28 volumes: 1916-1929 and 1916-May 1951. These two series represent the original base map set and a later map set showing revisions.

The UPA set provides one complete set covering the city in 33 volumes, 1976-1980. Earlier revisions of selected volumes have also been reproduced, covering 1964-1976.


ARRANGEMENT

A "Graphic map of volumes" at the beginning of each series' Volume 1 indicates the boundaries of each volume's coverage. A similar index map at the beginning of each volume, accompanied by a street index text, indicates the boundaries of each sheet covered by that volume. Each sheet is marked in an upper corner with the volume and sheet numbers.

The Chadwyck-Healey set reproduces the two earlier Sanborn map series in two separate series. The volumes are split among the 8 microfilm reels in this arrangement:

  1. First series. Philadelphia 1916-1929. Reels 1-4.
    • Reel 1 (= Pennsylvania reel 42). Philadelphia 1916-1929, volumes 1-7
    • Reel 2 (= Pennsylvania reel 43). Philadelphia 1916-1929, volumes 8-14
    • Reel 3 (= Pennsylvania reel 44). Philadelphia 1916-1929, volumes 15-22
    • Reel 4 (= Pennsylvania reel 45). Philadelphia 1916-1929, volumes 23-28
  2. Second series. Philadelphia 1916-May 1951. Reels 5-8.
    • Reel 5 (= Pennsylvania reel 46). Philadelphia 1916-May 1951, volumes 1-7
    • Reel 6 (= Pennsylvania reel 47). Philadelphia 1916-May 1951, volumes 8-14

    • Reel 8 (= Pennsylvania reel 49). Philadelphia 1916-May 1951, volumes 23-28

  • Reel 1 (= Pennsylvania reel 16). Philadelphia volumes 1-2
  • Reel 2 (= Pennsylvania reel 17). Philadelphia volumes 3-6
  • Reel 3 (= Pennsylvania reel 18). Philadelphia volumes 7-9

Van Pelt and Fine Arts Libraries own a number of mid- and late-nineteenth century and early twentieth-century atlases, most of which show building or lot outlines. Names associated with these atlases are George William Baist (1880s-1890s), G.H. Jones (1870s), Griffith Morgan Hopkins (1870s), Jacob E. Schiedt (1890s), James D. Scott (1870s), Samuel L. Smedley (1860s), Elvino V. Smith (1900s-1910s), J.L. Smith (1910s). Searching Franklin with keywords, e.g., "skey maps AND skey philadelphia", will identify Penn Library holdings.

The Free Library of Philadelphia's Map Collection is an excellent resource for Philadelphia maps. In addition to the country's largest collection of regional Sanborns and Hexamers, and an extensive collection of other atlases, the Map Collection holds three sets of aerial photographs for the Philadelphia area: Aero Service Corporation (1945-1950), Dallin Aerial Surveys (1930), and Regional Planning Federation of the Philadelphia Tri-State District (1929).
