Statistical data were examined to see the number of library volumes in four types of colleges as defined by the Carnegie Commission. These were comprehensive universities and colleges I and II and liberal arts colleges I and II. Statistically significant differences were found between liberal arts colleges I and II, but this was not so for comprehensive universities and colleges I and II. However, when sub-groupings based on enrollments were devised, significant differences did appear. A table of statistical data is included, and two methods for counting microform volumes are explained. (LS)
