It's not possible to accurately estimate the number of scholars and members of the general public who benefit from the organization's publications, because the institutions and university libraries that support the organization, by subscribing directly to and purchasing these publications, allow access to all faculty and students.

The research published by the organization is also available digitally through contracting consolidators and copyright clearing houses. Moreover, most content is eventually uploaded to open-access sites, available to all in perpetuity.
