ALA has a Honorary Membership list at https://www.ala.org/awardsgrants/awards/176/all_years
“Honorary membership may be conferred on a living citizen of any country whose contribution to librarianship or a closely related field is so outstanding that it is of lasting importance to the advancement of the whole field of library service. It is intended to reflect honor upon the ALA as well as upon the individual.”
Dr. Kathleen McCook recently created this list at https://en.wikipedia.org/wiki/American_Library_Association_Honorary_Membership with additional information and major accomplishments of the honorary members. It makes a great reference for the library historian!
