Self-archiving ultimately accelerates the process of sharing your data. How and what to self-archive is a difficult decision to make since both the publisher’s rights and the future ability to publish may be jeopardized by self-archiving too soon. For example, while the authors own a preprint version, it does not undergo peer review or other journal-style editing. Furthermore, publishers sometimes forbid the publication of previously available data, even if it’s only in a repository. Imagine trying to publish a work that has been deposited in a repository when the publisher doesn’t accept manuscripts that are available online elsewhere!
