Accepted author manuscript (AAM) Version of paper incorporating changes arising from peer review, but before publisher formatting. Also known as Author's manuscript, accepted manuscript and postprint.
Article processing charge (APC) Fee paid for papers published through the Gold route. The University has block grants from RCUK and the COAF to pay article processing charges. Authors are required to complete and submit a claim form.
CC-BY Creative Commons Attribution copyright license which allows for unrestricted reuse of content with the requirement that the source work is appropriately attributed. There are six different licenses but the CC-BY provides the most flexibility, and is required when open access is funded by RCUK or the COAF.
Charity Open Access Fund (COAF) A grant provided by seven participating charities:
  • Arthritis Research UK
  • Breast Cancer Campaign
  • British Heart Foundation
  • Cancer Research Uk
  • Leukaemia & Lymphoma UK
  • Parkinson's UK
  • Wellcome Trust.
Funds are used to pay for open access payments arising from research from one or more of these charities. Authors should complete and submit a claim form.
Double dipping Arises if a publisher seeks an unwarrantable increase in revenues by levying APCs for publication in a hybrid journal, while not providing a proportionate decrease in subscription costs.
Embargo period A length of time that publishers set before authors are allowed to make publications Green open access. Embargos may vary and further information can be found using the Sherpa/RoMEO tool.
Gold The Gold route achieves immediate online public open access via your chosen publisher, usually for a fee called an article processing charge (APC). Bristol researchers who are funded by RCUK or one of the COAF charities are eligible to claim for Gold Open Access charges. There are two gold options:
  • Hybrid journal; published under a subscription model with open access granted to individual articles accompanied by an APC payment.
  • Gold only journal; the cost of publication of papers is covered by the author paid APC payment, providing full open access to the reader.
Green The Green route involves the author publishing through the traditional route with researchers self-archiving preprints or postprints in an institutional repository or a subject specific repository such as ArXiv. Publisher embargo periods may be imposed for papers published through the green route.
HEFCE post-2014 Open Access Policy The HEFCE policy requires that all journal articles and conference proceedings with an ISSN submitted to the next REF are deposited in a repository within three months of acceptance. Authors should forward their acceptance email to
Hybrid journal Published under a subscription model with open access granted to individual articles on payment of a publishing fee or APC payment.
Postprint The version of a paper or article after peer-review but before publication. This version will contain revisions, and is often referred to as the accepted author manuscript. In some disciplines a paper may proceed through several iterations at peer-review.
Preprint The version of a paper or article before peer-review. A preprint may be the draft early version of a paper.
Publisher PDF The final version for publication including publishers typesetting and formatting. In many cases the author is not able to use the publisher's PDF file, and should make their own for the purposes of self-archiving. This version is also sometimes referred to as the version of record or publisher version. A small number of publishers will allow the publisher PDF to be archived in a repository, contact the relevant Research Engagement Librarian or the Open Access team via for further information.
Pure The University of Bristol’s research information system which collects, organises and integrates information about research. This is where research outputs can be self-archived to make them open access. The information in Pure is made available through Explore Bristol Research and is discoverable through Google and other search engines.
RCUK Open Access Policy RCUK aims to achieve immediate, unrestricted online access to peer-reviewed published papers free of charge at the point of access. Papers arising from RCUK funded research should be made open access, and a block grant has been provided to help facilitate this requirement for authors.
Self-archiving For the purposes of open access, self-archiving is the act of depositing an electronic version of a paper or article in an institutional or subject specific repository. This is usually the accepted author manuscript or preprint version.
SHERPA A service that aggregates publisher self-archiving policies to provide a quick source of information about publisher copyright policies and embargo periods. SHERPA/RoMEO provides self-archiving policies and SHERPA/FACT links this to information about funder compliance.
Validation The final step in the Pure process completed by the Open Access team. A record will be validated and made public via Explore Bristol Research once the accepted manuscript has been uploaded, the Pure record has been checked and any necessary embargo periods have been set. Authors will also need to forward their acceptance email to before a record can be validated.
Version of record The fixed version of a paper that has been made available by a publisher. This version will have proof corrections, been through copy editing and will include final formatting. The version of record is also sometimes known as the article of record, the publisher PDF or the publisher version.
