Government Documents Registry

HathiTrust is seeking a developer to Project staff documented possible methods for identifying items as U.S. federal government documents based on their bibliographic metadata, and continued work on an algorithm to detect relationships between items. These methods will be tested and refined in the coming weeks.

HathiTrust Research Center

Tim Cole and Peter Organisciak recently presented HTRC posters on HathiTrust metadata evaluation and large-scale text analysis at Digital Humanities 2014 in Lausanne Switzerland, July 7-12, 2014.  The following week, J. Stephen Downie and Megan Senseney conducted instructional sessions about HTRC tools and services across multiple workshops at the Digital Humanities Oxford Summer School, July 14-18, 2014.

Development Updates

Development activities by HathiTrust institutions included the following:

Authentication and Authorization

  • Enhancements to the workflow for updating access privileges for staff who have special access to restricted materials.

Collection Builder Application

  • Staff improved the application’s performance when sorting lists of items in large personal collections, and improved the accuracy of sorting multi-part monograph and serial volumes when date information is available.

Full-text Search

  • A determination that the INEX 2007-2010 Book Track  test collections would not be suitable for use in testing HathiTrust full-text search relevance ranking algorithms due to several issues, including missing relevance judgments and underspecified queries. Staff are in the process of analyzing the issues to design criteria for creating a suitable test collection.
  • Continued communication with the supplier of the high-performance storage system for full-text search and await a software update that is expected to resolve performance and stability problems.


  • The release of a new user interface “skin” for the Copyright Review Management System. This update brings the CRMS interface into closer alignment with the public-facing PageTurner interface, and will address presentation bugs and facilitate future changes.

Server replacement cycle

  • Staff continued installation of new full-text search servers, with revised plans to put them into service in August at the Michigan site and in September at the Indiana site.


Cumulative 12-month availability: 99.844%

Service was unavailable on Friday, July 25 from 6:30-8:30am EDT and full-text search was additionally unavailable until 9:15am EDT, when blocking measures were implemented against abnormally heavy search activity and all services were restored.

Personal collections were unavailable on Monday, July 28 from 5:00-5:10pm EDT for a database optimization designed to increase performance.
