In 2013, Oregon State University Faculty Senate unanimously passed an Open Access Policy.  One direct result of this policy is that OSU faculty retain copyright to articles published after the policy was passed.  Specifically, OSU faculty can distribute the accepted manuscript version (post peer review, pre publisher formatting) of their articles from their own websites, deposit them in repositories (such as ScholarsArchive@OSU and PubMed Central), use them in their classes, and develop derivative works.

The language surrounding the publication process can get confusing.  The NISO/ALPSP Journal Article Versions (JAV) Technical Working Group's recommendations, NISO RP-8-2008, provide a standard for describing the versions of scholarly journal articles. The recommendations define seven stages for journal articles:
Author's Original (AO): The original version of the article submitted by the author.
Submitted Manuscript Under Review (SMUR): The version of the article under review. This version is equivalent to what has been commonly known as the pre-print.
Accepted Manuscript (AM): The version of the article that has been accepted for publication. This version is equivalent to what has been commonly known as the post-print. 
Proof (P): The proof version of the article
Version of Record (VoR): The final published version of the article. This is also known as the "publisher version". 
Corrected Version of Record (CVoR): A corrected version of the final published version
Enhanced Version of Record (EVoR): An enhanced version of the final published version Below are the standard terms for different versions of an article throughout the publication process. 

Thanks to the OSU Open Access Policy passed by the Faculty Senate in 2013, faculty at OSU may self-archive any version of their article that precedes the VoR immediately to ScholarsArchive@OSU.
