October 19-23, 2009 is the first international Open Access Week.
Open Access Week is intended to broaden awareness and understanding of Open Access to research within the international higher education community and the general public.
Last years Open Access Day organizers SPARC (the Scholarly Publishing & Academic Resources Coalition), the PLoS (The Public Library of Science), and Students for FreeCulture are joined for 2009 by OASIS (the Open Access Scholarly Information Sourcebook); Open Access Directory (OAD); and eIFL.net (Electronic Information for Libraries).
Activities around the world are listed at Open Access Week.
Check out the week of talks at the University of Puerto Rico, the pre-week activities in Ireland, the PLoS competition for the best medical paper and the spirit of open access haiku contest from SHERPA.
