Traditionally, authors transfer their copyright to their publisher when publishing their work. Under this agreement, the author often gives up their legal right to reproduce, share, or create derivatives of their work.
Thankfully imperfect alternatives have been emerging within the scholarly communications realm. Most common is the model of Gold OA publishing, where you pay publication costs and license your copyrighted work to the publisher for them to reproduce and distribute. Depending on your interests, needs, and funding sources, this may not be the best solution for you.
In this section (which we’ll admit gets a bit repetitive), we strongly recommend you experiment with and try to use author addendums when negotiating with your publisher. While you may still be signing over the copyright to them, these addendums often protect your ability to distribute and use your own work without any additional costs.
