HathiTrust is Hiring

HathiTrust has opened searches for three positions to oversee core operations and advance our programs to expand access to US federal documents and to develop the shared print monographs archiving program.    Full details and requirements of each position are posted at:https://www.hathitrust.org/jobs.

HathiTrust Member Meeting to be held December 9 in Chicago

The 2015 HathiTrust Member Meeting will be held on December 9 at the Big Ten Center near O’Hare Airport in Chicago.  We ask all official member representatives to plan to attend or to designate an attendee who can, if needed, vote on behalf of their institution. Following the model of the 2011 Constitutional Convention, library directors from consortia that are HathiTrust members may also attend, although only the member representative for the consortia may vote.

We plan to begin at 9am and conclude by 3pm, with a continental breakfast available at 8am.  A detailed agenda will be sent to registered attendees in advance of the meeting. We expect the meeting to include an update on strategic initiatives, proposed by-laws changes, and an in-depth discussion of the planned Shared Print Monograph Archiving program, as well as finances, the legal landscape, and current priorities. 

There is no charge to attend the meeting, but we will ask attendees to RSVP by November 25, 2015. Registration information will be sent to member representatives.   A block of rooms are available for attendees at the Aloft Chicago O’Hare, adjacent to the Big Ten Center, and other hotels are located within walking distance of the Big Ten Center.  Please contact Melissa Stewart (mmstewa@hathitrust.org) if you  have questions.

Board of Governors Update

The HathiTrust Board of Governors held their summer meeting by telephone on July 29.  Executive Director Mike Furlough provided the Board with a mid-year budget report, an update on planning for the 2016 budget, and a progress report on the Federal Documents and Shared Print Monograph Archiving Initiatives.  Bob Wolven reviewed recent work of the Program Steering Committee, which he chairs.  The Board took action to approve plans for the 2015 Member Meeting, the 2015 Board of Governors election process and schedule, and proposals to fill a position to support the Shared Print Initiative, and also appointed two new members to the Program Steering Committee.  In addition, the Board discussed factors to be considered in developing formal membership criteria. 

Board of Governors Elections to Begin Soon

The HathiTrust membership will elect three new members to the HathiTrust Board of Governors in an election that will begin on September 28 and conclude on October 19.  The Nominating Period closed on August 24 and the final slate of candidates will be announced immediately before the election.  For more information about the 2015 Elections Process see:  https://www.hathitrust.org/elections2015​.

Locally-digitized Content

Cornell University and the Bentley Library (University of Michigan) began ingest of locally-digitized materials. Emory University, University of Maryland, Northwestern University, Columbia University prepared for submission of locally digitized materials. McGill University, University of Delaware, University of Missouri, and Yale University submitted additional materials for ingest.

Google-digitized content

University of Texas has begun work to include their Google-digitized materials in HathiTrust. This would include 500,000 in-copyright materials and 6,000 public domain materials.   The schedule for ingest is still being determined.

Bibliographic Data Management

The California Digital Library (CDL) loaded 96,183 new, and 112,035 update records.


Copyright Review

A summary of the determinations from HathiTrust copyright review activities in May is given below. See CRMS-US and CRMS-World for further information. The CRMS projects are funded by the Institute for Museum and Library Services.

US Federal Documents Registry

As of August 31, there are 651,200 open US federal documents in HathiTrust. 

An alpha version of the US Federal Documents Registry was launched in June. Currently the Registry includes 5,479,188 records, contributed by 42 different libraries. Project staff are currently working on incorporating additional records into the Registry, improving duplicate detection by exploring ways to parse item description information (enumeration and chronology), and identifying records for out-of-scope materials such as state government documents. Feedback on Registry functionality and content is welcomed and encouraged.  The Registry may be accessed at http://www.hathitrust.org/usdocs_registry/.

Near-term plans for Registry development include the incorporation of fuzzy text matching into the duplicate detection process, improving the Registry interface by adding an advanced search and displaying additional fields in records, incorporating a mechanism for removing records for out-of-scope materials, and developing better integration with the HathiTrust Digital Library.

Development Updates

Development updates and activities by HathiTrust institutions included the following:

Full-text Search

  • Work continued on a testing framework for relevance ranking.  Staff consulted with experts in information retrieval evaluation and received valuable feedback.  Initial improvements to logging were put into production.  An initial prototype for click logging (i.e., logging what the user clicks on in the browser) using “Balanced Interleaving” which allows comparing different relevance ranking algorithms and settings has been completed. Plans are to test the interleaving and click logging code and put it into production in September.

Collection Builder

  • A “Share this Collection” URL is now provided for ease of reuse. Additionally, a social toolbar has been added to share collections with popular services. 
  • Code to improve performance on large collections was put into production in August.

Page Turner

  • A social toolbar has been added to share items with popular services.
  • Full book PDF downloads are now logged directly to Google Analytics when the user downloads the final, built PDF.

  • Logging improvements were added to PageTurner to enable more detailed analysis of use and to be used in conjunction with the click logging (i.e., logging what the user clicks on in the browser) framework for Full Text search.

​​Fall Development Forecast

  • Continue work on a test framework for relevance ranking, including interleaving of search results for the comparison of ranking algorithms.​
  • Research ways to support alternative text formats.

Cumulative 12-month availability of repository access: 99.981% (+0.006%).

On Thursday, June 25, from 01:04-01:27 EDT users may have been unable to access HathiTrust due to a problem between one of the search servers and its underlying storage.

On Thursday, August 6, from 15:35-16:42 EDT some users may have had difficulty accessing HathiTrust services due to a network broadcast storm that severely crippled network traffic to services hosted at the Ann Arbor datacenter.

* 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.
