Official statement from the New York GSO service material:
"The term 'Conference-approved' describes written or audiovisual material approved by the Conference for publication by GSO. This process assures that everything in such literature is in accord with AA principles. Conference-approved material always deals with the recovery program of Alcoholics Anonymous or with information about the AA Fellowship."
"The term has no relation to material not published by GSO. It does not imply Conference disapproval of other material about AA. A great deal of literature helpful to alcoholics is published by others, and AA does not try to tell any individual member what he or she may or may not read."
"Conference approval assures us that a piece of literature represents solid AA experience. Any Conference-approved booklet or pamphlet goes through a lengthy and painstaking process, during which a variety of AAs from all over the United States and Canada read and express opinions at every stage of production."
