When authors work with publishers, it is important to determine who will own the copyright. This is done through a publishing agreement, where the publisher may require the author to transfer most of the copyright to them. This can affect where the work can be deposited , how it is made available and where it is used in future. Some publishers may instead grant the author a license to publish a version of their content whether that be preprint, postprint or publishers version. It is important for authors to be aware of the different approaches to publishing agreements and how they can impact their work.
