9.4 million books CUL 3.9, NYPL 3.5, PUL

2.0 5 Modules complete 2 planned for

construction: Modules 8 & 9

CUL manages transfers with quotas

Tours conducted once or twice every year

Columbia will occupy 5 aisles of new modules

NYPL plans to transfer 5.3 million books

Quotas will expand to 250,000 accessions per year (FY15)

ReCAP: Physical Plant

2 new modules 12 aisles each,

same length as aisle 5

Ground breaking in spring 2012, completed summer 2013

What else is there to look at?

What can it tell us?

What do we think it tells us?

How do we manipulate it?

CHARGES: Offsite vs. On Campus by Fiscal Year

Offsite On Campus

Page 14: Zack Lane ReCAP Coordinator January 24, 2012 ReCAP Columbia University.

ReCAPColumbia University

Zack’s Crystal Ball (extrapolation) Drop in total on campus charges: 399,208 Rise in total offsite charges: 29,282

◦ July-Dec = 51.87% of on campus, 48.59% of offsite)

User behavior: Faculty request offsite collections more and renew in greater proportion

Adaptation to technology takes time

Caveat: Causation is hard to prove

“Libraries” consist of multiple CLIO locations (collections)

Page 48: Zack Lane ReCAP Coordinator January 24, 2012 ReCAP Columbia University.

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)

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

Place of publication important
