A high-use title is any title that has been requested 5 or more times since accession
Includes both physical delivery and EDD Desire by staff to study high-use titles Initial purpose of ReCAP was to shelve low-
use collections Due to space need, selector decision and
patron trends, some titles may be considered higher- or high-use
Excludes: eng, fre, ger and ita

Area Studies vs System-wide
Area Studies System Wide
For several years there has been a steady decline for EDD requests
Likely due to e-access to current titles and purchase of backfiles
Individual patrons can have large effect on data (e.g. early 2009)
Pagination now required (August 2009) Patrons must have active borrowing
privileges to request EDD (August 2011)
