Deutsches bersee-Institut, 1990. This new directory was compiled in 1989 and replaces two earlier works from the 1970s, one on institutions, the other on collections of literature. It provides detailed information, obtained through a questionnaire and by site visits, on 210 institutions, though unfortunately the format does not always allow the reader a good overview of the data.
Indexes provide access to areas of specialization.
A new edition is in preparation that will take into account facilities in the new German states.
