With information on the type of Open Access, discipline and impact covering more than 55,000 journals, oa.finder helps researchers identify a suitable journal for Open Access publishing. To select a suitable place for publication, researchers can use the simple search mask to specify the type of publication they are planning, their role within the publication process, and their own research institution. The result list of possible journals can then be filtered, sorted and searched according to further criteria. In addition, information about the respective funding options is displayed. A search option for publishers that publish monographs, edited volumes and conference proceedings in Open Access is still in the works.

The oa.finder is based on publicly available data sources, such as the Electronic Journals Library (EZB), the DOAJ (Directory of Open Access Journals) and the Journal Checker Tool.
