HathiTrust Member Meeting

HathiTrust held its first annual Member Meeting on October 10, 2014. Meeting Notes, presentations, and other documentation from the meeting are posted online, as is a new blog post containing reflections on the meeting by Executive Director Mike Furlough. 

Research Center Request for Proposals

The HTRC released a Request for Proposals for Advanced Collaborative Support (ACS), a new launched scholarly service that pairs individuals with expert staff at the HTRC over an extended period of time, to facilitate computational research on the HathiTrust corpus and use of HTRC tools. Details are provided at the link above. Interest parties are invited to submit proposals by 5:00 pm on January 8th, 2015.


Locally-digitized content

HathiTrust advised Texas A&M University, Columbia University, Emory University, Yale University, and the University of Washington on issues of validating content, and provided information about content submission to the University of British Columbia.

Google-digitized Content

HathiTrust ingested more than 530,000 new public domain volumes from Harvard University, and more than 200,000 volumes that had previously be held in escrow by Google from Indiana University, Pennsylvania State University, and University of Illinois at Urbana-Champaign.

Internet Archive-digitized Content

HathiTrust communicated with the University of North Carolina, Chapel Hill about correcting problems with images and bibliographic data and about submission of new content.

Bibliographic Data Management

The California Digital Library (CDL) loaded 773,823 new or updated bibliographic records into Zephir.

Working Groups and Committees

Program Steering Committee

The Program Steering Committee (PSC) held its second in-person meeting in Washington, DC, on October 11th, the day following the first annual Members meeting.  In addition to reviewing work under way in the currently active working groups,the Committee received and began discussing a draft report and recommendations from the Government Documents Initiative Planning and Advisory Group. After further review, the PSC expects to forward the report to the Board in December, with recommendations for action.  The remainder of the meeting focused on four broad areas that have been identified for further planning and activity in the coming year:  Non-Text Formats; Quality Assurance and Validation; Services for Users who have Print Disabilities; and Metadata Strategies and Policies (view the planning briefs in these areas for more information). Through the remainder of the fall the PSC will use its biweekly calls to take up each of these areas in turn, and develop action plans for programmatic activities.

Government Documents Registry

Project staff continued to refine a relationship detection algorithm for US government documents, and hope to have an initial algorithm finalized by mid-November. Staff also continued to identify improperly cataloged records for US government documents in HathiTrust and to seek to determine the comprehensiveness of selected US government documents. An update of project activities for the past six months is now available from the Registry web page.

HathiTrust Research Center

On October 23rd, J. Stephen Downie, Jacob Jett, Peter Organisciak and Loretta Auvil of the University of Illinois and Pip Wilcox of Oxford University presented an overview of the HTRC at the 2014 Chicago Colloquium on Digital Humanities and Computer Science. Panel members presented on the following topics:

  • Introduction to HTRC (Downie)
  • WCSA/Collection Building (Jett & Wilcox)
  • Feature Extraction (Organisciak)
  • HTRC Bookworm (Auvil)

More information on HTRC’s panel at DHCS 2014 can be found on the conference website.

CLIR Fellows Sayan Bhattacharyya from the University of Illinois and Matt Davis from North Carolina State University were awarded a CLIR micro-grant to research and develop use cases for new tools to conduct large-scale algorithmic analysis of text corpora. The use cases are intended to support the development of tutorials for such tools, including tools to be used in the HathiTrust Research Center.

Development Updates

Development updates and activities by HathiTrust institutions included the following:

Authentication, Authorization, and Access

  • Continued to add support for “access profiles” (see the Update on September Activities), including modifications to mechanisms that display relevant rights information in OAI records, and watermarks in the HathiTrust PageTurner.

Full-text Search

  • Fixed a bug affecting indexing and full-text searching of an estimated 50% or more of Chinese and Japanese volumes. Searching of these materials is now significantly improved.
  • Performed benchmarking tests on the new high-performance storage system after installing new pre-release software. The system now performs as expected, and will be put into service when a software release suitable for production deployment is obtained from the provider.
  • Made further enhancements to the search index update and release process that will be used with the new storage system.

Server Replacement Cycle

  • Completed installation of new full-text search servers at the Indiana repository instance, and transitioned those and the new servers installed at Michigan in September into service.

Storage Replacement Cycle

  • Purchased and completed an early installation of approximately half of the new storage for the 2015 cycle. The storage was purchased to accommodate substantial repository growth this fall, which exceed earlier projections.


Cumulative 12-month availability of repository access*: 99.949% (+0.105%)

Permanent links to HathiTrust volumes, including links from the HathiTrust catalog, were not working on Thursday, October 9 from approximately 4:30-5:10pm due to an outage with the CNRI Handle Service.

A bug in Zephir resulted in a failure to export full catalog metadata on October 31. The problem was corrected on November 4. As a result of the problem, the aggregate “hathifile” generally produced on the first of each month was not available until November 4. 

* Repository access refers to page viewing and full-text search functionality, i.e., user-facing applications. It does not refer to preservation or storage infrastructure, which is under continual operation.
