Open Access Publishing @ the Library: OA Publishing Outside Our Library

Green OA Publishers

Green open access means that the publisher locks the final published form of the paper behind a paywall, but the author takes steps to ensure that it’s freely avalaible elsewhere.

The form of the paper that is made available varies: ideally it’s the final published form; sometimes it may be the final accepted manuscript, as it was when the author last touched it, before the publisher typeset it.

Often, Green OA uses institutional repositories (IRs). Another common option is a subject repository, of which the best known is arXiv — the vast preprint archive for maths, physics and astronomy, and occasionally palaeontology. Another (rather weak) form of Green OA is individual researcher collections on web-pages. The key point is that the author has to make this happen, rather than leaving it to the publisher.

Gold OA Publishing

Gold open access means that that publisher, which creates the final published form of the paper (i.e. usually a PDF) makes that final published form freely available...The key point is that the publisher is responsible for making the work freely available.

Well-behaved Gold-OA publishers will also do things like ensuring the papers are indexed in reference databases like PubMed, and that they are archived in schemes like LOCKSS and Portico. The key point is that the publisher is responsible for making the work freely available.

Hybrid OA Publihers

A growing number of publishers are adopting “hybrid models” where journal articles are made Open Access on payment of an Article Processing Charge despite the journal being part of a subscription bundle.

This is seen by some publishers as a transition method from subscription-based access to Open Access.

  • A hybrid model means that the basic business model of the journal is the subscription model though publishers offer authors the possibility to pay for Open Access (sometimes called the “Open Access option”)
  • The term “Double Dipping” is used because publishers receive money twice: the subscriptions are still paid by the universities and authors pay for Open Access
  • Hybrid journals, on average, cost more than full Gold OA journals. For example, hybrids are over 50% higher than the mean of fully OA journals from non-subscription publishers. Ref: Monitoring the Transition to Open Access.
