Access rights to the contents of the individual journals are indicated with "traffic lights". Entries are searchable on journal level.

In the late 1800's, Dutch physician and feminist Aletta Jacobs and her husband C.V. Gerritsen began collecting books, pamphlets and periodicals reflecting the revolution of a feminist consciousness and the movement for women's rights. By the time their successors finished their work in 1945, the Gerritsen Collection was the greatest single source for the study of women's history in the world, with materials spanning four centuries and 15 languages. The Gerritsen curators gathered more than 4,700 publications from continental Europe, the U.S., the United Kingdom, Canada, and New Zealand, dating from 1543-1945. The anti-feminist case is presented as well as the pro-feminist; many other titles present a purely objective record of the condition of women at a given time.

The Middle Eastern & North African Newspapers collection includes publications from across this dynamic region, providing unique insights into the history of individual countries, as well as broad viewpoints on key historic events from the late nineteenth century through the present. Key topics include the decline of colonialism, the collapse of the Ottoman Empire, the Suez Crisis, the Cold War, the rise of the petroleum industry, twentieth-century pan-Arab movements, both World Wars, the establishment of the state of Israel, the Iran-Iraq War, and the recent Arab Spring. Researchers will find a wealth of unique content from the Middle East and North Africa, much of which has never been digitized or available as open access material. Content in the Middle Eastern & North African Newspapers collection is predominantly in Arabic, but also includes key titles in English and French. The collection comprises mostly out-of-copyright, orphaned content. Subscribing institutions also receive access to five in-copyright titles from the region: Jumhuriyah (Egypt), Filastin (Palestine), Al Akhbar (Lebanon), Al Riadh (Saudi Arabia), and Ad Dustour (Jordan).

The Max Planck Journal Index provides holdings of a great range of printed journals available within the Max Planck Society. Besides, it contains metadata of electronic journals as loaded from the EZB. The database is updated regularly from the ZDB (twice a year) and the EZB (monthly).

Access to full text archives (incl. 2007) of selected titles with a subject focus on medicine, chemistry and biology has been enabled.

The ZDB is the world’s largest specialized database for serial titles (journals, annuals, newspapers etc., incl. e-journals). The ZDB contains more than 1 million bibliographic records of serials from the 16th century onwards, from all countries, in all languages, held in 4000 German (and some foreign) libraries, with holdings information. It does not index individual journal articles.
