The Bibliography of the History of Art (BHA) contains abstracts and indexes of current publications in the history of art, including scholarly journals, conferences, book, exhibition reviews, and exhibition catalogues. The records consist of bibliographic citations, abstracts, and indexing. Note that the database search includes BHA, covering 1990-2007, the International Bibliography of Art (IBA), covering the years 2008 and part of 2009, and the Répertoire de la litterature de l'art (RILA), one of the predecessors of BHA, with records that cover 1975–1989.

This database covers international publications about German history from the early days until the present. Die Datenbank erfaßt und erschließt internationale Veröffentlichungen zur deutschen Geschichte von den Anfängen bis zur Gegenwart.

Traditionell liegt der Schwerpunkt der Sammlung auf Künstlermonographien (auch Ausstellungskatalogen), kunsttopographischer Literatur zu den Regionen und Orten Italiens sowie auf Quellenschriften

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).

The goal of OAIster is to create a collection of previously difficult-to-access, academically-oriented digital resources that is easily searchable by anyone.
