Monographs : all records with format “am”

Substantial holdings of monographs
published between 1950 and 1990
Post-2003 materials were transferred directly
to ReCAP at the time of acquisition
Approximately 30,000 new acquisitions per
year are sent directly to ReCAP
Further analysis indicates that recent
publications are requested by patrons at a
higher rate

Physical delivery has been constantly rising as
more collections are accessioned
EDD volume had been dropping per capita
due to accessibility of electronic backfiles
In January 2009, Health Sciences Library
began transferring serial collections
EDD volume began to rise both in aggregate
and in proportion to physical delivery
