Sherpa Romeo is a tool that can be used when researching journals to publish in or when determining how works published in certain journals can be shared. Sherpa Romeo aggregates, summarizes, and includes direct links to journal policies, making it easier to research and compare open access policies and requirements. A graphic of the typical publishing workflow for an academic journal article (preprint, postprint, and published) with open access sharing rights per SHERPA/RoMEO. This is a summary of the text already on this page about the differences in versions of work..

Article Versions

When using Sherpa Romeo it is important to know the differences between Published, Accepted, and Submitted versions of scholarly articles:

Published Version - This is the version of record published in the journal. It has been through peer review and copy editing, so it will usually contain publisher logos and other enhancements.
Accepted Version - This is the final version of a scholarly work that has been peer-reviewed and accepted for publication by a journal, but before copyediting, so it does not contain the publisher's logos or other enhancements.
Submitted Version - This is the version of a scholarly work prior to formal peer-review.
Locations for Sharing

It is also important to know the differences between institutional repositories, non-profit and preprint repositories, commercial scholarly commons, and other websites:

Example - UDSpace, DASH, EliScholar
Funder-designated Repository - A digital library that an organization that sponsors research has specified as the place where authors should deposit any publications that were supported by grant funding from the organization.
Example - PubMed Central
