Before depositing the file it is necessary to check whether the publisher allows for publishing the text in the Jagiellonian University Repository. This can be done through the Sherpa service, which uses four colours to indicate different publisher strategies for pre- and post-printing. Preprint is understood as a version of publication before peer-review. The postprint is the version of the publication after the review. 

Green                          preprints, postprints and final versions of the publisher can be archived
Blue                             postprints and final versions of the publisher can be archived
Yellow                         preprints can be archived
White             archiving is not formally allowed by the publisher


It is often the case that a publisher restricts making available in the repository only the publishing version, but allows the preprint and/or postprint version to be deposited.

Unfortunately, this is a source that gives knowledge mainly about foreign publishers. If the policy is not specified, ask for the publisher's consent.

Additional information about the publisher's policy can be obtained from the DOAJ (Directory of Open Access Journals), where you can find a list of open, peer-reviewed scientific journals from all fields of science.
