Open Access

"By open access to research literature, we mean its free availability on the public internet, [...] without financial, legal, or technical barriers [...] "
(Extract from the Budapest Open Access Initiative)

Through an open access publication, your publications can be freely available to everyone worldwide and are therefore easier to find and quoted more frequently.

Strategies of Open Access

There are two strategies to implement Open Access, the green and the golden road.

Golden road: means the primary publication in an Open Access journal
Green road: the simultaneous or subsequent deposit of already reviewed and published publications in an open access online repository

Gold Open Access - Publication in an Open Access journal

"Gold Open Access" means publishing in an Open Access Journal. Open Access Journals run a peer review process to insure scientific quality. Access worldwide is free of charge and public.
Open Access Journal Publishers often charge a fee for each article in opposite to charging for a journal subscription. The fee is usually paid by the author or their affiliated institution. The price for publication fees depends on the respective journal. According to the Open APC initiative, the price can range between 100 € and 4000 €. The estimated average price for publishing fees paid in Germany is approximately 1500 €.

  • A suitable Open Access journal can be found in the Directory of Open Access Journals DOAJ. It provides an overview of more than 10,000 refereed Open Access Journals (February 2015).
  • Even Monographs are increasingly being published via Open Access. The Directory of Open Access Books (DOAB) provides an overview of individual titles and publishers.
  • The Open APC initiative is committed to the disclosure of publication fees. The publication costs of different institutions can be viewed and evaluated
