Operating expenditures, including many automation expenditures, have doubled since 1986, but have remained at
relatively stable levels of investment. The total salary expenditures median has increased only slightly over the past four
years (average rate of 4%). Monograph expenditures continue to increase, but in 2007–2008 have increased at a lower rate
than the consumer price index (CPI). The annual consumer price index, included in Graph 4, provides a comparative
reference for the increases in library expenditures.
