There are many good reasons to choose to publish in an Open Access (OA) journal. Your research may be more discoverable by colleagues and researchers worldwide. You may also have more control over permissions to post and share your research with others. Posting copies of your research papers in ISU's Digital Repository or similar research repository is often called self-archiving.
When you are considering journals for article submission and publication, it's very important to know in advance what are the journal's policies on copyright retention, self-archiving permissions, and more.
One of the main reasons to choose an Open Access journal is that you are more likely to be able to use your published article in ways that help you promote your work, such as posting it within an institutional repository or sharing it elsewhere. But an increasing number of journals that are not totally Open are allowing authors to retain some rights over their articles too.
As an author, consider your rights when you're looking for suitable journals for your article. Important questions to ask:
SHERPA / RoMEO is a unique database that helps you know what rights specific journals will allow you to retain!
Just search your journal by name in SHERPA / RoMEO. You'll quickly see if you can retain copyright, and which version(s) of your work (pre-print, post-print, publisher's version) you can post ("self-archive") and where, plus any special conditions you'll need to follow.
You can use the information you find to guide your decision on which journals to choose for your publications.
