Review of ReCAP operations◦ Physical plant◦ Systems

Outline
ReCAPColumbia University
9.7 million books CUL 4.0, NYPL 3.5,
PUL 2.2 5 Modules complete 2 planned for
construction: Module 8 & 9 have broken ground, expected to open June 2013
CUL manages transfers with quotas
ReCAP: Physical Plant
ReCAPColumbia University
Tours conducted once or twice each year
CUL and ReCAP computer systems do not dynamically interact
CUL systems are designed to keep in sync with ReCAP systems
Patrons place requests via CLIO; different levels of request permissions are in place for staff in order to manage special collection
On such a large scale and in context of complex systems problems may ensue…
ReCAP Systems
ReCAPColumbia University
The Science Libraries have primarily general collections at ReCAP
Circulating and non-circulating collections
Items in poor physical condition do not circulate
Lots of information and instructions can be found on the Sciences/ReCAP website
Sciences at ReCAP
ReCAPColumbia University
Four basic categories of data◦ Accessions◦ Requests◦ Delivery◦ Circulation
Detailed information can be found at the ReCAP Data Center website
Website now includes introductory presentations for all basic categories AND analysis

System-wide Requests by Hour
ReCAPColumbia University
Delivery Items physically delivered to circulation
desks Requests outpace deliveries – indicating
Science collections going to other locations more often
May be due to closure of several locations Patrons developing new habits

Sciences: Requests vs. Deliveries
Requests Deliveries

Request Rate Request rate is a measure of collection usage It is the percentage of ReCAP collections
requested during a twelve-month period Provides staff one way to gauge overall use of
offsite collections Request rate is one factor used to structure ReCAP
facility staffing model Patron access to offsite collections is excellent:
dynamic with few failures Measured two ways:
◦ Annual ◦ Lifespan
