The indexing of the unprocessed digitized microfilms is work in progress. It is conducted, film by film, by members of the Wikipedia Projekt Pressearchiv in cooperation with ZBW. Some films are fully indexed, some only top-level, some not at all. The list of film sections below is therefore incomplete.
Grayed-out section labels indicate just an arbitrary cut at the beginning of an new film. The topic may have already started on the previous film, and the number of images may comprise much more than the given topic.
For intellectual property law reasons accessible only from ZBW reading room.
Material may exist on microfiche. Access is only possible at the Hamburg site of the ZBW - please contact us via the feedback address at the foot of this page.
