Graph 2 displays the skyrocketing expenditures for serials (in comparison to monograph expenditures). Note that Table 2 and
Graph 2 have been revised since 2005–2006 and no longer include Serial Unit Cost or Serial Subscriptions. Beginning with
2006–2007, ARL libraries are reporting unduplicated counts of serial titles rather than subscriptions.
