Among the non-cartographic materials in the collection is a file of some
12,000 4-by-6-inch cards that represent part of Hammond's printing history
from the early 1900s to the mid-1990s. This is primarily a record of the
publications that Hammond produced for other companies. The basic data
contained in these records changed over time but usually included such
information as the customer's name, type of material printed, and number of
copies printed, which could range from a few hundred to hundreds of
thousands of copies. |
