About Prange Posters

Welcome to the Gordon W. Prange Collection Posters and Wall Newspapers database. The Prange Collection is the most comprehensive archive in the world of Japanese print publications issued during the early years of the Occupation of Japan, 1945-1949. It contains 261 posters and wall newspapers. They include political posters, public health posters, safety posters, posters in education, local government publications and many other types of posters. 

The Prange Collection Posters and Wall Newspapers database is the realization of a long-term goal of the Prange Collection staff members to make the Prange Collection materials searchable and accessible from anywhere around the world. In contrast to a majority of the Prange Collection holdings, Prange’s Posters and Wall Newspapers are in public domain, which makes it possible to provide them open access.

The Prange Collection Posters and Wall Newspaper database includes approximately 250 items. They were issued from October 1945 to November 1949 across more than twenty prefectures nationwide. Additional items are currently being digitized and will be added to the database as soon as they are available.

The Diamondback began publication on January 1, 1910, under the name The Triangle. The paper changed title multiple times until its name became The Diamondback with the June 9, 1921, issue.

  • Triangle, January 1, 1910 – October 14, 1914
  • M.A.C. Weekly, October 21, 1914 – May 31, 1916
  • Maryland State Weekly, September 1916 – January 30, 1919 (variant titles M. S. Weekly and M. S. C. Weekly during this time)

Publication frequency has varied over the years. Initially, the paper appeared biweekly, moving to a weekly, then a daily format on weekdays during the academic year. At present, publication occurs online on a weekday basis during the academic year, and paper copies appear on Mondays during the fall and spring semesters.
