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.
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.
