Open Access and Depositing your Research: Open Access Glossary

What is a hybrid journal?

A hybrid open access journal is a subscription journal in which some of the articles are open access. This status typically requires the payment of a publication fee (also called an article processing charge or APC) to the publisher.

What is an APC?

An APC is the fee paid to the publisher to cover the cost of making research open access via the gold open access route.

What is double dipping?

This is the practice whereby institutions effectively pay publishers twice – once via a journal subscription fee and secondly via article processing charges (APCs) for gold open access articles in subscription journals.

What is a DOI?

Digital Object Identifier: A unique identifier for an online document, used by most online journal publishers. As the DOI is unique to the publication, and the underlying metadata will include the most up-to-date location of the file, referring to an online document by its DOI provides more stable linking than simply referring to it by its URL.

What is an accepted version?

It is the version of your output that

  • has been accepted for publication
  • has been peer-reviewed
  • but has generally not yet had the publisher's layout and typesetting applied

This can often be a Word version of your publication but some publishers work with templates from the submission stage so it is necessary to store all versions of your output until you receive confirmation of acceptance.

Most publishers allow this (and only this) version to be made available in an open access repository, usually after an embargo period has passed.

This is also known as a post-print or author's final version.

What is a pre-print?

This is the submitted version of a work before peer review.

What is an embargo period?

Publishers often specify an embargo period with green open access. This can vary from 6 months to 48 months. REF policy stipulates that STEM subjects (Panels A  and B) can have a maximum embargo of 12 months, for all other subject area of 24 months (Panels C and D). Individual funders may specify shorter embargo periods. If the journal you wish to publish in has a longer embargo please contact the BRIAN team for advice.

Sherpa Romeo is a useful guide for journals. Some publishers such as Elsevier have a separate journal specific list of embargo periods for UK authors. BURO staff are happy to advise on this.

What is Gold Open Access?

  Gold Open Access is where the author makes their article Open Access in a journal, usually for a fee known as an APC. This journal may be exclusively  Open Access, or it may have a mixture of Open Access and subscription-only articles.

What is Green Open Access?

Green Open Access is where the author publishes in a journal and then deposits a version of this article into a subject or institutional repository such as  BURO. This is also known as self-archiving.
