About
What is HathiTrust
Universal Digital Library
Common Goal
Single Entity but Partnership of Many
Libraries
Goals
• Reliable and comprehensive archive of
materials converted from print…co-owned
• Ensure the long-term preservation of content
• Improve access …to meet the needs of the coowning institutions
• Coordinate shared storage strategies
• “public good” …sustaining the historical record
• Simultaneously …centralized …open
Background
History
• Michigan Digitization Project 2004
• “…U of M shall have the right to use the U of
M Digital Copy, in whole or in part at U of M's
sole discretion, as part of services offered in
cooperation with partner research libraries
such as the institutions in the Digital Library
Federation…”
History
• Collective Agreement with CIC Announced in
June 2007
– U of Michigan and U of Wisconsin Projects already
underway
History
• In 2007, CIC agreed to establish a shared
digital repository
• University of Michigan and Indiana University
initial leaders of this effort

Partnership &
Resources
Partnership & Resources (1)
• Funded for a initial 5 years with
base-funding from partners
• Budget – separately held within
UMich budget system, managed
by the Executive Committee
• Cost Model – Per GB cost of storage per year with a
one-time fee on new content to build a capital fund
• Review in 3rd yr of each 5 yr period
Partnership & Resources (2)
• Staff/Expertise – highly integrated
– Project managers, IT and communications
staff, copyright experts, administrators (UM,
Indiana and UC taking the lead)
• Working groups
• UM recently hired a Digital Preservation Librarian
• Shared development space

Partnership & Resources (3)
• Toward a Cloud Library
– CLIR, Mellon Foundation
– OCLC Research, NYU, HathiTrust, Recap Libraries
• Objective: Characterize the near-term opportunity for externalizing
management of academic research collections leveraging capacity
of large-scale shared print and digital repositories*
• Outcomes: opportunity and risk assessment based on aggregate
collection analysis; draft service agreement enabling generic
consumer library to selectively outsource preservation and access
of low-use research collections to large-scale print and digital
repositories
*From the RLG Partner Update January 7, 2010
Partnership & Resources (4)
• CRL TRAC Audit
– Portico and HathiTrust assessments timely
– “Certification will augment CRL’s strategic archiving of
print, and support a responsible transition to electroniconly formats where appropriate.”
– Work with UC to design shared print journal archiving
effort
– “With this hybrid strategy CRL hopes to enable its
community to accelerate the shift to electronic-only
resources in a careful and responsible manner.”

Partnership & Resources (5)
• New cost model
• Based on benefits to institutions
– Public Domain
– In-copyright
• Volumes “held”
• Covered by Settlement
– Print replacement, users with print disabilities; research
corpus
• Not
– Section 108; expand via authentication
Partnership & Resources (6)
• Timeline:
– Implement in 2013
– Accept new partners now with costs based on
overlap calculations
• Requirements:
– Print holdings database
– Update mechanisms
– Manual remediation
Partnership & Resources (7)
• Print holdings database will also benefit
– De-duplication
• Compromises user experience, obscures collection
development needs
– Management of print volumes
• Information to withdraw volumes (journals)
– Legal uses of copyright materials
• Section 108, 121, ADA uses will depend knowledge of
which institutions own(ed) which mate

Technology – Architecture
• Inbound validation, standards-based
object storage and related metadata
• Storage in Ann Arbor and Indianapolis
• Encrypted backup to 3rd location
• Rights database for rights metadata
• Online catalog as source and storage for descriptive
metadata
Technology - Ingest
• Automatic validation in GROOVE
– Check barcode check digit using Luhn algorithm
– Fixity check on JPG2000, TIFF, UTF8 using MD5
– Well-formedness and embedded metadata check
on JPG2000, TIFF, UTF8 using JHOVE
Technology - Repository
• Simple filesystem layout
– One directory per volume, zip file and METS file
– Use of a namespace allows for conflicting
identifiers
– Namespaces for institutions and, if needed, types
of identifiers within the institution
Technology – METS Object
• Why METS?
– Can serve as Archival Information
Package and a Dissemination
Information Package
– Designed to record the relationship between
pieces of complex digital objects
– Can be created automatically as texts are loaded
or reloaded
– Preservation actions (PREMIS)
Technology – METS Object
• What’s there?
– metsHdr with an ID and CREATEDATE
– 2 dmdSecs: Marcxml and mdRef
– amdSec containing one techMD with PREMIS
metadata
– fileSec with 4 fileGrps (zip, images, OCR, hOCR)
– Physical structMap tying together files with
metadata (pg. numbers and features)
