The idea for the San Francisco Declaration on Research Assessment began at the 2012 ASCB Annual Meeting. As one of the initial DORA signatories, the ASCB does not promote its publications by the Journal Impact Factor. The ASCB also implemented a policy that does not allow promotional materials distributed by the society at its annual meeting to advertise journal impact factors.

Reflecting its deep concern about the widespread misuse of journal impact factors to evaluate the outputs of scientific research, ASCB will not permit advertisement of journal impact factors in any of its publications or in promotional materials that it distributes on behalf of exhibitors at the ASCB Annual Meeting.
