Open Access publishing can be done in several ways in order to make your research results freely available and thus enhance the effect of your publications.
You can publish in a subscription based journal and deposit a copy of your article in an open archive like DiVA (self-archiving), or you can publish in an Open Access journal.
Publish in a subscription based journal and in an open archive (DiVA)
Two out of three journal publishers allow self-archiving of scholarly articles, which represents 95% of all academic journals (source: Eprints.org
, July 2011). These include most of the big journal publishers such as Elsevier, Springer, Nature Publishing Group and AAAS (Science).

Publish in an Open Access journal
Open Access journals are freely available academic journals. They are subject to peer review in exactly the same way as traditonal scholarly journals, but they are financed in ways other than subscriptions. Authors usually retain copyright to their articles.

Guard your rights
Copyright always belongs to the author of a text from the outset, but when a text is published, the publisher usually requests the copyright to be transferred from the time of publication. This means that it is the publisher and not the author, or authors, who control how the publication can be used and disseminated.
By using alternative agreements you can retain some or all of the rights to your own publication.
Here are some examples of alternative agreements:
- SPARC Author Addendum
– various additions to agreements for journal articles giving the authors increased rights including the right to self-archive the article
- Copyright Toolbox
– an alternative licence for publishing journal articles and various kinds of drafts that can be used as addenda to publishing agreements
- Creative Commons
– various licence agreements all of which give the authors extended rights. These licences can be used for all kinds of publications
- European Commission's FP 7 Open Access pilot
– includes an addendum to agreements for the publishing of research findings that have been financed by the European Commission's 7th Framework Programme and are part of the programme's Open Access Pilot
