SEPTEMBER 2012 RESEARCH LIBRARY ISSUES: A QUARTERLY REPORT FROM ARL, CNI, AND SPARC
Figure 6. electronic Resources vs. total Materials, yearly increases in average expenditures, 1993–2011
Figure 6 contains data on several items, which previously had been collected only in the ARL
Supplementary Statistics. These data are especially useful because they reflect monies spent on all
electronic serials, while the ARL Statistics categories of “serials purchased” and “serials expenditures”
include only those journals that provide full-text electronic versions to their subscribers. The nature of
what is a serial purchase is shifting. E-books now are coming to libraries as subscription packages. And
multimedia products are challenging the traditional notions of serials and monographs.
Not only have electronic materials expenditures grown sharply in the past two decades, they have
grown at a rate far exceeding that of library materials expenditures overall. Figure 6 shows a sharp
growth every year of the past two decades in electronic materials expenditures, anywhere between two
and ten times faster than total materials expenditures have grown. The growth rate appears to be slowing
down, possibly indicating that an equilibrium position has been reached.
