Access to Out-of-Print and Brittle or Missing Items

One of the lawful uses of in-copyright works HathiTrust has been pursuing is to provide access on an institutional basis to works that fall under United States Copyright Law Section 108 conditions: works in HathiTrust that are not available on the market at a fair price, and for which print copies owned by HathiTrust member institutions are damaged, deteriorating, lost or stolen. As a part of becoming a member, institutions are required to submit information about their print holdings for fee calculation purposes. We have also been requesting information about the holdings status and condition of works, to facilitate uses of works where permissible by law (specifications for HathiTrust holdings data are available at http://www.hathitrust.org/print_holdings).

As of December 2012, we are using the holdings status and condition information submitted by United States member institutions, in combination with information about the market availability of works stored in the HathiTrust rights database, to determine whether or not access to applicable in-copyright works in HathiTrust is allowed. The specific terms of access are as follows:

  • Access is only available to users affiliated with HathiTrust member institutions in the United States, and only from U.S. soil.
  • In order to gain access, users from member institutions must be authenticated into HathiTrust via Shibboleth using their institutional login.
  • Print copies of the works in HathiTrust must be owned currently or have been owned previously by the institution’s library system.
  • The number of users who can access a given digital copy at a time is determined by the number of print copies held (or previously held) in the library system. If a library system only has one print copy, only one user at a time will be able to access the digital copy.

A general scenario for how out of print determinations are made and communicated to HathiTrust is available in the HathiTrust rights database documentation: http://www.hathitrust.org/rights_database#op.  Additional information on the service is available at http://www.hathitrust.org/out-of-print-brittle.

HathiTrust Bylaws

The Board of Governors completed a draft of HathiTrust bylaws, which was distributed to partner institutions in early December for comment. The Board is working on a final version with consideration for partner comments. The final version will be put forward to partners for voting in January.

Research Center Video

The Research Center released an informational video, following on the UnCamp that was held earlier in the fall of 2012. The video can be accessed at http://www.hathitrust.org/htrc.

Most-accessed Volumes in HathiTrust

This month we are including a new metric in our newsletter: the most accessed works in HathiTrust by pageview count. A table of volumes is included at the end of the update.


Local Digitization

Staff at the University of Michigan met to discuss the next steps for HathiTrust’s ingest tools, created to aid institutions in validating and packaging locally-digitized content prior to deposit in HathiTrust. A conference call is planned in January, which will include members of several partner institutions that have been working with the existing tools, to discuss possibilities and options for the future. HathiTrust continued discussions about deposit of locally-digitized materials with the University of Illinois, and responded to questions from McGill University.

Internet Archive Digitization

HathiTrust ingested new content from Penn State University and loaded records for content from the University of Florida and University of North Carolina-Chapel Hill. Ingest of volumes from Florida and UNC, and additional volumes from Penn State, is expected to occur in January.

Working Groups and Committees

Working groups and committees in HathiTrust may have an operational or strategic focus. See http://www.hathitrust.org/working_groups for more information.


User Support Working Group

A summary of issues received by the User Support Working Group is given in the table at the end of the update.


Bibliographic Data Management

California Digital Library (CDL) continued to work with staff at the University of Michigan on preliminary testing of data exports from Zephir, the new HathiTrust bibliographic management system under development by CDL. CDL and Michigan staff continued to plan for the upcoming period when Zephir and the bibliographic management system at Michigan will be run in parallel, prior to the full transition to Zephir.

Copyright Review

A summary of the determinations from HathiTrust copyright review activities in December is given below. The numbers this month reflect a different methodology for aggregating statistics. In previous months, the number of Reviews was given, and the number of volumes reviewed that were Opened. In the majority of cases, volumes are reviewed more than once (by more than one person). This meant that the number of Reviews reported was larger than the number of actual volumes reviewed. Similarly, the number of volumes Opened represented volumes that may have been determined in more than one review to be in the public domain. The table below provides a more accurate representation of the number of volumes where a determination was made, and what the determination was. We will use this representation going forward.

IMLS Quality Grant

The project team will present a research poster at ALA Midwinter in Seattle, during the Preservation Administrators Interest Group Meeting on Saturday, January 26.  The poster will focus on digitization error related to material characteristics of a book. The project team continues to focus on more complex analyses of the data collected in the past year and also on presentation of the findings. Additional findings and results will be posted on the project website later this month: http://hathitrust-quality.projects.si.umich.edu.


Staff at the University of Michigan revised the list of modules for mPach, to reflect recent changes in the planned system architecture.  An extensive conceptual workflow for ingest of an mPach Submission Information Package into HathiTrust has been devised and will be finalized soon. Michigan staff finalized plans for modifications to the HathiTrust Data API to support the retrieval via the API of JATS XML, derivative formats, and supplemental materials that may be associated with a JATS XML article.

Development Updates

Full-text Search

Staff at the University of Michigan released a bug fix for the Solr edismax query parser and a new index into production in late December (See the Update on November Activities for details.).  These changes will significantly improve the precision of CJK (Chinese, Japanese, and Korean) search results.

Michigan staff began preliminary analysis of HathiTrust document length statistics. The results of the analysis will aid in designing tests of length normalization features for the new relevance ranking algorithms available in Solr 4.0. Staff built a test index using the new relevance ranking algorithms available in Solr 4.0 (DFR, BM25. IB).  Experiments using the test index will begin in January.

Staff at Michigan made a final selection of high-performance storage for full-text search and completed pricing negotiations (see the Update on November Activities for background). Purchase of the storage is expected to be complete in January, with installation and testing to follow soon after in late January or early February.

Web Applications

Michigan staff completed the removal of sensitive information from source-controlled HathiTrust application code to designated system-level locations. Staff also completed the separation of privileges for accessing application databases. Different classes of applications now connect as different database users with different privileges.

Michigan staff began to implement improvements to the display of special access messages (e.g., for works that are out of print and brittle) in the mobile version of PageTurner.

The PageTurner scroll view now advances by full pages when the navigation controls are used (e.g., next page button), rather than advancing by half of a page at a time.

The HathiTrust feedback form now detects content and metadata-related feedback submissions by CRMS (Copyright Review Management System) reviewers, pre-filling problem tickets with CRMS-specific information to simplify the management of support requests.


No outages were reported in December.

HathiTrust sends notice upon discovery and resolution of unscheduled outages and in advance of scheduled outages and maintenance work that may result in an outage. We welcome and encourage additional recipients for these notices. If your institution is not receiving outage notifications and would like to, please contact feedback@issues.hathitrust.org.
