What is Area Studies? ◦ Oops, I didn’t exactly know (it’s not “Lehman”)

Language/subject based selection Focus on two CLIO locations:

◦ “Area Studies Collection” = off,glx and off,leh Pamela helped focus topic: language, high-

use titles and request rate New challenge: language codes

Accessions / Requests by CLIO Location


“Libraries” consist of multiple CLIO locations (collections)


Request Request typically begins immediately after

transfer Volume has leveled off system-wide in

past three years May be explained by charge/renewal trend Monthly request volume in phase with

academic calendar 50% more requests in Fall and Spring than

Summer system-wide Data for small and low-use collections is

noisy

System-wide Requests by Hour

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)
