SPARC’s Author Addendum is a legal instrument that allows authors to modify a publisher’s copyright transfer agreement and keep key rights to their work, including the possibility of making it open access and widely available. For this project, I revised and edited SPARC’s accompanying explanatory literature about the Author Addendum and helped create four new deliverables for the information suitable for today’s information environment. At the conclusion of this project, authors who want to maintain their right to share their work widely and openly will have an updated resource for understanding the basics of copyright and open access.
