On 11 April 2003, the
Howard Hughes Medical Institute held a meeting for 24 people to discuss better access to scholarly literature. The group made a definition of an open access publication as one which grants a "free, irrevocable, worldwide, perpetual right of access to, and a license to copy, use, distribute, transmit, and display the work publicly and to make and distribute derivative works, in any digital medium for any responsible purpose, subject to proper attribution of authorship" and from which every article is "deposited immediately upon initial publication in at least one online repository". ==Significance==
