Open Access Week is an annual scholarly communication event focusing on open access and related topics. It takes place globally during the last full week of October in a multitude of locations both on- and offline. Typical activities include talks, seminars, symposia, or the announcement of open access mandates or other milestones in open access. For instance, the Royal Society chose Open Access Week 2011 to announce that they would release the digitized backfiles of their archives, dating from 1665 to 1941.[1]
