Academic
A review reported in 1975 of the acquisition of whole collections to libraries during the period 1940-70 as reported in College and Research Libraries and College and Research Libraries News, involving 1,454 collections and 301 libraries, showed that, among academic libraries reporting acquisition of collections, the receipt of collections was distributed unevenly. 15% of the academic libraries accounted for 66% of the collections acquired by academic libraries. In more detail, 21.5% of the public academic libraries accounted for 66% of the collections acquired by that type of library, while 10.5% of the private academic libraries accounted for 62% of the collections acquired by that type of library.
