The Open THESEUS Archive (OTA) gives free access to the digital collection of THESEUS acknowledged publications. This archive is managed according to the principles of the Open Access Movement, and the Open Archive Initiative and meets the Special clause 39 of the THESEUS project stating that all final published articles (or final peer-reviewed manuscripts) resulting from FP 7 projects should be deposited into a repository. The OTA will try to include all A1 publications, articles from conference proceedings and poster presentations resulting from the THESEUS project.
