WU authors may want to consider these options; sometimes another repository, such as a subject repository, makes more sense for your purposes.
School of Medicine authors: use Digital Commons@Becker.
Authors from Arts & Sciences, Law, George Warren Brown School of Social Work, School of Engineering & Applied Science, Sam Fox School of Design & Visual Arts, and Olin Business School: use Open Scholarship; contact your subject librarian to begin the process.
Traditionally authors transfer all or selected rights to a publisher as part of the publishing process. The author keeps some rights by standard agreement, by using an addendum, or by negotiation. Most commonly, authors keep the right to self-archive a final author manuscript version (either before or after peer review). Sometimes there is an embargo. Less commonly a final published version can be self-archived with or without an embargo.
79% of scholarly publishers worldwide give some form of blanket permission for authors to archive a version of their articles in an accessible place, and even the 21% that don’t can be pressured to allow such archiving.
Attitudes about sharing articles before peer review vary with disciplines. Attitudes and practices are also changing. New models for peer review are also developing, such as open peer review and portable peer review.
Sometimes your publication agreement will require you remove preprints after peer review or update them to a postprint/final author manuscript version.
A few repositories specify post-peer-review content only; here are a few examples of repositories which include preprints. You can find more in OpenDOAR - Directory of Open Access Repositories
Some funders are beginning to allow or encourage preprints in pre- or post-funding reviews. Funder Policies page on the ASAPbio site. [ASAPbio is a scientist-driven initiative to promote the productive use of preprints in the life sciences.]
Professor of Communications at Georgia State University talks about keeping the right to archive a final author manuscript version. She uses the GSU version of WU's Open Scholarship and she also uses Academia.edu.
