This declaration was signed by key players in the open-access movement at a meeting organised by the Open Society Institute in Budapest in February 2002.

It calls for barriers to open-access publishing to be removed, with the aim that research articles from all academic fields be made freely available on the Internet.

Other individuals and organisations are now invited to sign the declaration to pledge their support and help ensure a transition to open-access publishing. More than 3,000 individuals and 200 organisations have added their name to the initiative.
