The University of California Libraries: A Plan for Development (1977)

154 The University of California Libraries
be allotted for each of these users. The resulting requirement for
user space, based on the projected enrollments given in Chapter I, is
indicated in Table 23.
Space for Non-Book Materials. The remaining category--library
materials--can be broken down further into two broad sub-categories:
bound volumes (both monographs and serials), and non-book materials
(maps, manuscripts, pamphlets, recordings, documents not counted as
volumes, and microforms). For convenience, the "non-book" category
was defined to include equipment (such as microform readers) required
to use non-book materials. As in the case of staff and users, the
size of this sub-category was calculated and projected to the year
1987/88. Counts of all non-book materials presently in the UC libraries
were collected from the campuses, and the growth rates for
each category were then projected by linear regression on the statistics
for the past ten years. To project the number of microform
readers, the ratio of readers to total microforms was computed separately
for each campus, and it was assumed that campuses would
continue to acquire readers in the same ratio as their microform
collections grew.
The space required for most non-book materials was calculated on
the basis of the so-called "Wellman Standards," developed by Vice
President Wellman some years ago. The allowances, by category, are
shown in Table 24. For manuscripts, the space needed was calculated
from the actual experience at Berkeley's Bancroft Library, which has
a large collection. Documents not counted as volumes were assumed to
require the same space, on the average, as pamphlets.
The resulting projections of space required for non-book materials
are shown in Table 25.
Space for Bound Volumes. The last category (or rather, subcategory)
to be considered is the amount of space required for bound
volumes. This amount may vary greatly, depending on the method of
shelving adopted. In an open-stack library, as virtually all of
those at the University of California are, the space required varies
from 10 to 15 volumes per asf, or stated conversely, from .066 to .1
asf per volume. Using other methods of shelving, however, the space
