CONTINUING A THREE-YEAR UPSWING, THE LATEST CIRC STATS SHOW A 5% INCREASE

In 1997, the Index of American Public Library Circulation was 116, a 5% increase from the 1996 circulation index of 110.

The index of expenditures rose 7% from 138 in 1996 to 147 in 1997. The index of expenditures in constant 1990 dollars was 120 in 1997, a 4% increase froth 115 in 1996.

The index scores are computed by dividing the library's reported 1997 circulation and expenditure totals by its corresponding 1990 figures and multiplying by 100. The resulting scores are ranked from highest to lowest, and the median score is the index value. The index of spending in 1990 dollars is calculated by dividing the expenditure index in each year by the Consumer Price Index (annual average for all urban consumers) converted to a 1990 base.
