Originally supported by Saarland University and State Library (SULB) since 2003, it was operated by the Leibniz Institute of Psychology (ZPID) from 2016 on.
In 2022, publications from PsyDok were moved to the subject repository PsychArchives maintained by ZPID.
PsyDok was set up with the support of the DFG (Deutsche Forschungsgemeinschaft) as part of the third-party project "Digital Psychology Information" at the Saarland University and State Library (SULB).
In 2016, when funding for PsyDok ended, ZPID took over the operation of the platform from SULB.
To ensure the long-term availability of the publications stored in PsyDok, they were included in the disciplinary repository PsychArchives maintained by ZPID in 2022.
