Carnegie Mellon University Libraries is hosting a new online tool developed by Science Commons and the Scholarly Publishing and Academic Resources Coalition (SPARC). The tool enables authors to generate an addendum to attach to their publisher's copyright transfer agreement in order to retain certain rights. For example, authors can retain the right to re-use their work and to make it available open access on their web site or a discipline repository. Authors can choose from among several addenda depending on the rights they want to retain. Click on the link below to connect to the addendum generator.
