Many publishers permit authors to upload the Final Author Version (sometimes called the author accepted version or post-print) of their manuscript to their Institution's OA repository.
Depending on the publisher, there may be an embargo period, and/or a set statement, which must be applied prior to the Final Author Version being made accessible in the University Open Access Repository (OAR).
You can find out more about publisher's Green Open Access policies via the Sherpa/RoMEO website.
When you submit your paper to a journal, you will be asked to sign a Publisher (or Author) Agreement. This specifies the rights that you transfer to the publisher, often including a statement about whether or not you can deposit a version of your paper in an institutional repository.
Consider publishers' policies on sharing publications via an OA repository when developing your publication strategy and before signing the Publisher Agreement.
To retain rights enabling you to deposit your publication in an OA repository, you may wish to consider submitting an Author Addendum. Here are some examples:
Items deposited in WARP are assessed by the Library for copyright restraints (as well as other restraints e.g confidentiality, contractual).
If it is permissible, a version of the research output will be made Open Access in the OAR. Uploading the Final Author Version of a published output increases the likelihood of the output being made discoverable and accessible in the OAR.
Prior to deposit, and prior to publication, it is expected that researchers will have gained permission from third parties where required..
The University's Research and Copyright website is a good starting point for managing copyright within your publications
The University Research and Copyright website states that it is good practice to inform end-users what they can do with your research outputs (e.g. download or print for personal use; adapt the work for educational or non-commercial uses etc.)
Sometimes due to copyright restrictions your research outputs in the OAR will only be accessible by request. For request only items an email will automatically be forwarded from the OAR to the author/creator for mediation.
Whether or not you can accept the request to share the full-text of your publication will depend on what rights you have retained as an author. You may need to refer back to the Publisher Agreement you accepted when submitting your paper.
Some publishers make their policies on sharing really clear, like Royal Society of Chemistry:
Often, publishers allow you to share:
