Ulrich M hlert. The aim is the fullest possible documentation of all relevant institutions, although the foreign research institutions and archives could not be described in full detail. The directory is arranged in chapters by archives, libraries, research institutions, institutions for political education, organizations, museums, memorials, journals, and other institutions.
Archives constitute the largest part, making up over one third of the total volume.
Within each chapter the arrangement is by place. Each entry lists persons in charge, financial backing, publications, collections and finding aids, and opening hours if the collections are public. The most important institutions are described in fuller detail at the end of the volume. More than 500 institutions are listed, most German but also some foreign. Larger institutions, such as the foundations funded by political parties, are listed more than once, for example under archives, libraries, and research institutes, which makes it easier to find the desired information.
