Cambridge Core is the online books and journals platform from Cambridge University Press replacing Cambridge Journals Online (CJO) and Cambridge Books online (CBO). From August 2025, the MPG will have access to over 50.000 e-books via the Evidence Based Acquisition (EBA) model for a period of three years. Additional content may have been licensed by individual Max Planck institutes. Max Planck authors and volume editors are entitled to publish their books open access. The costs are covered by the MPDL. Further details are available on the MPDL website.
