Journal of Mammalogy (May 1975) 56(2).
Mammalogy is the only systematic discipline that has previously undertaken periodic (that is, more than one) surveys of its holdings in North American collections. The first such survey (reported on by Howell, 1923) pertained to mammals in collections as of April of 1922. The report of the second survey (Doutt et al., 1945) summarized collections of mammals in North America as of 1943. The report of the third survey (Anderson et al., 1963) pertained to specimens of mammals in North American collections as of 1962. At that time, it was assumed that to prepare an updated report on North American collection resources of the discipline of mammalogy at a regular interval of about 20 years would be a worthwhile undertaking.
