The Scholar's Copyright Addendum Engine will help you generate a PDF form that you can attach to a journal publisher's copyright agreement to ensure that you retain certain rights.
This addendum gives you non-exclusive rights to create derivative works from your Article and to reproduce, distribute, publicly perform, and publicly display your article in connection with your teaching, conference presentations, lectures, other scholarly works, and professional activities.
You retain sufficient rights to grant to the reading public a Creative Commons Attribution Non Commercial license or similar license that allows the public to re-use or re-post your article so long as you are given credit as the author and so long as the reader's use is non-commercial.
