Addenda to agreements
According to the Open Access Directory (OAD) an author's addendum is a proposal to modify a publisher's standard copyrights. If agreed, it allows the author to retain the key rights, specifically the right to publish in Open Access.
This tool helps the author who does not feel at ease in negotiating the terms of contracts with publishers or who is not familiar enough with copyright laws or does not know the best terms to support Open Access. Carefull, because of its nature (an amendment proposal), a publisher may or may not accept the addendum.
SPARC organization offers an addendum in a version for the United States and for Canada which can be an inspiration if the below proposal by the SNSF does not fit your needs.
For the articles published by UNIGE, authors shoud add systematically an Addenda Creative Commons to the publishing conditions in order to benefit from the withholding of their rights.
