This research extends the "Purdue studies" of research library growth, presenting results that include library statistical trends during a 35-year period, 1951-1985. It serves to update Purdue's 9-report series (1965-1973) and is a validation study of Purdue's growth forecasts, 28 of which were published in 1965, then revised in 1971.…

Longitudinal studies are examined and statistical details are appended. (Author/LRW)
