Open Science means open access to
1) research publications and
2) research data, as well as
3) openness and transparency of the research process.
Open Access publishing is achieved by publishing in
1) open electronic journals or
2) by self-archiving in a university's institutional repository.
Open access publishing means granting the scientific community and the general publics rights to read, copy, print and link to the entire publication. Open access publishing means free dissemination of scientific information.
In Open Access publishing, the copyrights of the work remain with the author.
APC (article processing charge)
An APC is a fee paid to the publisher to make an article free at point of access (Gold OA or Hybrid OA).
Double dipping
Double-dipping describes the situation where a journal charges an APC on top of its normal subscription fee if an author wishes to make their particular article OA. In effect, the institution is paying twice. (Hybrid OA)
Embargo
A period of time defined by the publisher during which the author can not publish a self-archived open access copy of the publication in question. Embargo periods are typically from 6-36 months. The embargo period starts from the date of publication.
Final published version/Publisher PDF
The paper or article in the format in which it appears in the publication (i.e., the final version with the proper layout).
Institutional Repository
A university's or research facility's online database of their OA works. Repositories do not undertake peer review but do hold material that has been peer reviewed elsewhere. In addition repositories can hold 'grey literature' such as Theses, Discussion Papers, Datasets and other material for example Theseus.
Parallel publishing
The paper or article is published in a journal by a publisher, but a copy (usually the final draft) is made available OA in a repository. (Green OA)
Post-print/Final draft/Author accepted manuscript
A paper or article that has been peer-reviewed and accepted for publication but hasn't yet been laid out for publication by the publisher.
Pre-print
A draft version of a paper or article that hasn't been peer reviewed.
