Save the Date: HathiTrust Member Meeting

The HathiTrust bylaws passed in 2013 call for “an Annual Meeting of the Members...for the transaction of such business as may come before the meeting.”  We are pleased to announce that our first Annual Meeting will be held in Washington, DC on Friday October 10, 2014.  

We expect the meeting to include progress reports on ballot initiatives, official business, and opportunities to discuss future strategy. More details on location, schedule and agenda will be forthcoming in the next few weeks.  For now we ask all official Member Representatives to plan to attend this meeting.  If a representative cannot attend, a designate may attend in his or her place. 


Locally-digitized content

HathiTrust ingested a second batch of locally-digitized content from the University of Illinois and prepared to ingest materials from Boston College. HathiTrust also began conversations about ingest with Penn State University and Yale University, and continued communications about ingest with Emory University, University of Illinois at Urbana Champagne, and University of Washington.

Internet Archive-digitized content

HathiTrust began ingest of content from McGill University (see http://bit.ly/1xSm5Aq) and corresponded with University of Massachusetts, Amherst about ingest of new materials.

Google-digitized content

Many volumes scanned from partner institutions by Google in the last year were not ingested due to a change in a quality metric provided by Google that HathiTrust uses to create thresholds for content that enters the repository. In June, HathiTrust updated its use of the metric to restore the quality threshold for Google-digitized content to its previous level. The update will eventually bring more than 200,000 new volumes into the repository. 


Copyright Review

A summary of the determinations from HathiTrust copyright review activities in June is given below. See CRMS-US and CRMS-World for further information.

Government Documents Registry

Project staff continued to develop strategies to identify and make relationships between publications based on bibliographic information. This included work on rules to normalize descriptive terms and enumeration and chronology information, and rules to merge records. Staff continued to investigate methods to identify gaps in metadata, and began to think more concretely about how to engage the community in efforts to identify gaps and duplicate volumes.

Development Updates

Authentication and Authorization

Staff deployed the new system for managing users who have special access to restricted materials (e.g., for copyright or quality review). The system includes functions to register new users for specific time frames, renew access with appropriate authorization, and automatically expire access, as well as back-end scripts for individual and batch renewal or expiration.

Full-text Search

The software update that is expected to resolve performance and stability problems with the high-performance storage system for full-text search was delayed, and staff continued regular communications with the storage supplier on its availability. In the meantime, staff made improvements to the new daily index update process that is currently running in a test mode on the new storage system to more smoothly handle the large data updates that occur when the search index is fully rebuilt.

Staff investigated the suitability of the INEX 2007-2010 test collections to inform choices about relevance ranking algorithms for HathiTrust full-text search. 

Tom Burton-West wrote the second in a series of blog posts: “Practical Relevance Ranking for 11 Million Books, Part 2: Document Length and Relevance Ranking”.

PageTurner and Image Server

Staff prototyped new imgsrv capabilities for continuous text (e.g., JATS encoded articles without page breaks) in PageTurner, demonstrating in-article search.

Server replacement cycle

Staff began installation of new full-text search servers. The servers are tentatively planned to be put into service in July.


Cumulative 12-month availability: 99.867%

No outages were reported in June.
