SIUC Author AddendumAn author addendum is a supplementary agreement between an author and publisher. It accompanies the agreement required by the publisher and signed by the author which governs the terms of an article’s publication. The recommended addendum for SIUC authors informs the publisher of the University’s Open Access Policy and its terms, including the granting of a non-exclusive right to the University to distribute the article via the institutional repository, OpenSIUC. While not required to establish the priority of the University’s rights, it clarifies the rights of all parties and may help to avoid misunderstandings. So, it is recommended that the addendum be used for each article submitted to a journal.
