Review of ReCAP operations◦ Physical plant◦ Systems

Data◦ What there is to look at◦ Basic analysis: accession, requests and circulation◦ ILL/EDD◦ System-wide trends

Outline


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


Tours conducted once or twice each year

https://www1.columbia.edu/sec/cu/libraries/bts/recap/quotas.html

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


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


https://library.columbia.edu/content/librarywebsecure/bts/recap/projects/engineering.html



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


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
