Cloud Library

Overview
 The cloud library and this pilot project
 Brief overview of HathiTrust
 Findings
 Expectations
Cloud Library, not cloud computing
 Similar but vastly different
 Necessity/desire to share resources
 Multiple digital and print repositories
 Repositories can now move into a “cloud” that will
become a shared network resource
 What infrastructure needed?

Perceived need
 Already good support of other “virtual” shared
services, e.g., ILL, doc delivery
 What exists in off-site storage and digital
repositories that isn’t currently accessible?
 Collection development mechanisms need to
discover accessibility and preservation statuses
 How should we build such a service for consumers?
Demand for services
 Multiple, sometimes overlapping, reasons
institutions will be interested in being part of a cloud
library
preserving titles that are rare and/or special in some
manner
 remove titles that are duplicated across many institutions
 added value of shared materials in digital repository
(discovery, search)
 contributing to a public good

Partners in pilot
 NYU – model customer
 Acute space pressures; major library renovation
 Limited mandate to build local collection of record
 ReCAP – model supplier
 Large-scale shared academic storage collection
 HathiTrust – model supplier
 Large-scale shared digital repository
 OCLC Research and CLIR – consultants & convener
A bit about HathiTrust
 To contribute to the common good by collecting,
organizing, preserving, communicating, and sharing
the record of human knowledge
materials converted from print
 improve access …to meet the needs of the co-owning
institutions
 reliable and accessible electronic representations
 coordinate shared storage strategies
 “public good” …sustaining the historical record
 simultaneously …centralized …open

Growth of HathiTrust
 Includes ingest of materials not from Google (GBS)
Intersections
Material that NYU
can obtain through
HT dependent on
copyright status –
enhance ‘local’
collection
opportunities for institutional cooperation
shared policy frameworks
joint service agreements
increased operational efficiencies
Material that NYU can
relegate with a high
degree of confidence
HathiTrust
Material that
NYU can
already source
through existing
ILL – enhance
local collection
N=3.8M
N=2.3M
N=7.6M
ReCAP
that NYU
may choose to
relegate based on
copyright/ availability
ReCAP
Material that NYU
may choose to
relegate with
appropriate service
level agreement
The Cloud Library
 Increased reliance on a network of collections and
services with a robust underpinning of shared policy
and service infrastructures that are jointly owned by
participating libraries
 Naturally, as number of participants grows, value of
partnership increases
 Goal of pilot study:
service expectations for both digital and print
repositories
 cost/benefit analyses for sharing resources
 processes for discovery of shareable titles

Process for discovery of overlap
 Ingestion on a monthly basis
 Checking of OCLC numbers (without can’t be
processed)– use of xID to derive more
 New data structure…

HathiTrust: Looking forward
 Ingesting from 4 institutions (UC, Indiana,


Wisconsin, Michigan), more to come
Moving from off-site storage scanning to main
libraries
Result: slight changes in number of PD volumes
Change in membership …broader base of institutions
for cost-sharing
Future contracts will mostly be picklists
Internet Archive ingest starts this winter/late fall
Completion of TRAC certification
Requirements and benefits
 Service expectations for both HathiTrust and ReCAP
 turnaround time
 continuity of operations
 access privileges
 With HathiTrust, all are par for the course
 As partners in the cloud library…
 preservation of texts and metadata
 longevity and perptuity
 trust and reliability
 access to titles not held by library (comprehensive)
 opportunity for voice in HathiTrust development
