The United States Holocaust Memorial Museum has made the first two volumes of their Encyclopedia of Camps and Ghettos 1933-1945 freely available on its website at
Volume I includes the major concentration camps, their sub-camps, SS
construction brigades, and early camps set up by the police, SA and SS
shortly after the Nazis seized power. Volume II includes ghettos in
German-occupied territories. Each volume matches the physical format
of the book, and each consists of two pdf files. The place name index
is in the back of the second part of each volume. Each signed article
includes citations and bibliographies for further research. Overview
articles provide additional information, and are worth reading.
Future volumes will be made available online after the print volume
has been available for a few years. Volume III- camps and ghettos in
countries allied with the Nazis- is scheduled to be released in print
The volume II will be helpful to any patrons researching their Jewish ancestors and volume I will be helpful for the families of American soldiers who help liberate the camps.
