Figures  reflect   Materials   Expenditures   only   from   those   institutions   that   reported   nonzero   figures   for   Total   Electronic   Resources.  
*In     a recent   review   of   past   Supplementary   Statistics   data,   some   figures   previously   published   in   these   columns   were   found   to   be   incorrect   and   subsequently   revised.  
+  Includes   only   nonzero   responses,   to   be   consistent   with   past   Supplementary   Statistics   reporting.    Statistics   that   include   zeroes   can   be   found   on   page   51.
