The UMD Libraries have invested heavily in organizing, processing, and
preserving the Prange Collection. As a result of severe shortages in the
post-war years, Japanese publishers were forced to use poor quality, high-acid
content paper, and the publications from these years are rapidly deteriorating.
Since the early 1990s, the UMD Libraries have partnered with the
Diet Library of Japan (NDL) to preserve and provide access to the materials
in the Prange Collection, which fill a gap in NDL's historical record. Between
1992 and 2001, the Prange magazine and newspaper collections were microfilmed.
In 2005, the current project to digitize the 71,000 Prange books began. Major
progress has been made toward achieving the UMD Libraries' goal of preserving
the entire Collection so that it will be fully accessible.
