Embargo refers to a period of time defined by the publisher, calculated from the publishing time of the original publication, during which the author has no permission of publishing a self-archived open access copy of a publication
APC (article processing charge) refers to a fee often gathered to cover the costs of gold open access publishing, e.g. the costs of the peer-review process.
Pre-print refers to the work as it was when submitted to the publisher for peer-review, i.e. pre-peer-review version of the article.
Post-print (also final draft or author accepted manuscript) refers to the post-peer-review version of the work as it was before the publisher created the final layout for the work (logos, etc.)
Final published version (also publisher PDF) refers to the work in the form in which the publisher disseminates it.
What is open access to scientific information? (Source: European Commission background note on open access to publications and data in Horizon 2020)
Open access can be defined as the practice of providing on-line access to scientific information that is free of charge to the reader. In the context of R&D, open access typically focuses on access to 'scientific information', which refers to two main categories:
Benefits of open access for researchers
Research indicates that open access publication leads to significant increase in citations in some disciplines: 300% to 450% in medicine; 170% to 580% in physics/astronomy; and 200% to 600% in agricultural sciences (Swan, 2010, The Open Access citation advantage: studies and results to date, http://eprints.ecs.soton.ac.uk/18516/).
What are 'Green' and 'Gold' open access?
They are two main and non-mutually exclusive routes towards open access:
‘Green' open access (also called self-archiving) means that the published article or the final peer-reviewed manuscript is archived by the researcher in an online repository before, after or alongside its publication. Access to this article is often delayed (‘embargo period’). Publishers recoup their investment by selling subscriptions and charging pay-per-download/view fees during this exclusivity period. This model is promoted alongside the 'Gold' route by the open access community of researchers and librarians, and is often preferred.
'Gold' open access means that a publication is immediately provided in open access mode by the scientific publisher. Associate costs are shifted from readers to the university to which the researcher is affiliated. Gold open access fee is often called article processing charge (APC) and can amount to a few thousand euros/article. A large number of journals, including those of high prestige and/or high impact factors have also developed self-archiving policies ('Green' open access) that are compatible with the policies of research funding bodies such as the European Commission for Horizon 2020.
