Bohemia-Online is a joint project of the Collegium Carolinum and the Bavarian State Library. It is funded by the German Research Foundation (DFG).

Bohemia-Online provides open access to all issues of Bohemia since the journal was first launched in 1960. They can be accessed, downloaded and printed via full text search or a differentiated search. New issues of the journal appear partly directly online, partly with a time delay. For the essays there is a moving wall of 24 months, the other sections appear simultaneously with the print edition of Bohemia-online.

The aim of Bohemia-online is to make research results of Bohemian Studies openly and free of charge accessible and thus to intensify the communication within and beyond the subject boundaries. The project partners guarantee quality assurance and reliable long-term archiving. In this way, they also want to contribute to the promotion of the Open Access idea.
