Open Access
• CERN Convention (1953) contains what is
effectively an early Open Access manifesto:
– “… the results of its experimental and theoretical
work shall be published or otherwise made
generally available”
• Signatory of Berlin Declaration
– Author grants
• free, irrevocable, worldwide, perpetual right of access, …
– Store in repository
• Unrestricted distribution, interoperability, long-term
archiving, …
