If your article is published in a journal using the traditional subscriber model, most publishers provide Open Access redemption (hybrid gold route), which can be chosen for a separate fee when submitting the publication. In this case, the publication is freely available (even without a subscription) to anyone on the publisher’s website.
It is possible to provide open access to publications published in a journal using a subscriber model without paying an Open Access redemption fee, this is an option for authors to self-archive (green way).
Each publisher regulates the possibility of self-archiving in different ways, distinguishing between different versions of publications, which can be:
preprint: This version is the first manuscript the author sends to the publisher for peer review. (Archiving the preprint version is only recommended if there has been no significant change to the content after peer review!)
postprint: The author's manuscript after the last peer review, after that there is no change in the content of the publication.
publisher version: A version that usually appears on the publisher's website, edited, supplemented with page numbers and other information.
Self-archiving means that the author can place a certain version of the submitted publication (preprint, postprint, publisher's version) in the repository operated by his institute with possible restrictions, if the publisher allows it. The Sherpa-ROMEO database provides indicative information about the opportunities provided by individual publishers and journals; legally, the author's contract with the publisher is decisive, and it is also worth studying the publisher's website. (The term "self-acrhiving" is suggested as a keyword)
If the full-text version can be placed in the repository, the publication becomes freely available to readers, which increases the accessibility of the publication to other researchers.
The restrictions set by publishers are usually as follows:
Embargo: Self-archiving is only possible after a specified period of time (usually 6-12-24 months). When uploading to the repository, it is possible to specify the embargo period, so the uploaded document will only be publicly available after the specified date.
Indication of the source: The uploaded manuscript must contain the publication (bibliographic) data, the DOI and a note indicating the type of the manuscript (“Manuscript as accepted” or “Submitted version, accepted without substantial change”). Some publishers may require other parts of the text to be added, e.g. for Springer: The link must be provided by inserting the DOI number of the article in the following sentence: "The final publication is available at Springer via http://dx.doi.org/[insert DOI]."
The repository of Semmelweis University is available at https://repo.lib.semmelweis.hu, but uploading can be done through the MTMT system. Of course, this requires first entering the bibliographic data of the publication, assigning the author(s), institute(s), then uploading the full-text version using the Operations / SWORD upload button.
The steps required to implement self-archiving can be summarized as follows:
1) Check which version the publisher allows and with what restrictions it can be uploaded.
Sherpa-ROMEO (http://sherpa.ac.uk/romeo/), or publisher's website, contract study.
2) You need to get the best possible version of the publication depending on the permissions, this is most often the postprint version, as archiving the publisher version is rarely possible.
3) The manuscript must be supplemented with various details (See Indication of source)
4) The publication must be uploaded to the MTMT, the necessary assignments must be made
5) Upload from MTMT to the Semmelweis Repository (and / or other repository)
6) After acceptance by the repository, the link must be armed in the MTMT.
