Open access (OA) - research output is made openly available in digital form (a publishing business model and an ideal)
APC (Article Processing Charge) - a charge which some journals or publishers charge for making an article open access. Also called open access fee or author fee.
Creative Commons (CC)-license - a copyright license attached to online material by its creator to let other users know what rights they have and do not have to re-use - share, modify, copy, sell the material.
Digital Object Indentifier (DOI) - a permanent identification number for digital documents
Embargo - a restriction on how soon after publishing an article can be made openly available in an open repository or elsewhere on the Internet
Gold open access - the publisher makes the scholarly article openly available (in some cases against a fee, in other cases for free). Two main models: full open access publication and hybrid publications.
Hybrid open access - a form of gold open access, when an article published in a subscription journal is made open access using an additional service against a fee. In a hybrid journal, only some of the articles are openly available and the rest behind paywalls.
Gratis open access - the publication is free to read online, but the reuse of it might be bound up with restrictions.
Green open access = parallel publishing = self-archiving = a version of an article primarily published in a subscription journal is archived in an open archive or repository, for instance the university's institutional repository or open archive.
Libre open access - the publication is free to read online but also void of technical or legal restrictions for reuse (for instance as communcated with the help of Creative Commons licences)
Sherpa/Romeo - an online database which contains information on publishers' and journals' green open access/copyright policies.
Post-print - the author's accepted manuscript: the peer reviewed version of an article, in which some changes may have been made after first submission, but which has not been typeset or copy-edited by the publisher. The very last version edited by the author. (Not the same as the proofs, which usually are typeset).
Pre-print - submitted version, the manuscript of an article which has not yet been peer reviewed.
Parallel publication = self-archiving = green open access - the publication is made openly available in an open repository, for instance the open research information database of the university.
Open access is when research output is made available for free online. It helps spread research results both within the research community and outside it. Readers can access, read, use, copy, print and link to open access publications.
OA publications should be Gratis OA, free to be read, linked to and printed without cost to the reader, but also Libre OA, void of copyright barriers which hinders the reuse and circulation of it (for instance with the help of open creative commons licenses).
Open access comes in three main forms:
Gold Open Access is when the publisher makes the article available, either as a:
