Read our new blog post  about building HathiTrust collections.
The new Board of Governors met in Chicago in conjunction with the ARL membership meeting in May. The group spent some time before the meeting identifying priorities, focusing primarily on the organizational work of the Board. The Board quickly formed an Executive Committee, as stipulated in the Constitutional Convention ballot proposal . The new Executive Committee members include Paul Courant, Carol Diedrichs, Laine Farley, Sarah Michalak and Bob Wolven. Another group chaired by Pat Steele was charged with initiating the process to assemble by-laws. This group will also attend to issues such as the duration of the appointment of the Executive Committee, and expects to conclude its work by the end of November. A third group will be formed to focus on the development of a Charter.
The Board of Governors will meet by teleconference for the next several months, targeting one meeting per month, as the process of developing by-laws moves forward. In these meetings the Board plans to review HathiTrust’s past work, which will include a review of the HathiTrust budget as well as HathiTrust’s committees and working groups. Although it was not able to discuss HathiTrust’s existing committees and working groups in detail in Chicago, the Board expressed a deep appreciation for the work the Strategic Advisory Board, the Collections Committee, and the current operational working groups and committees have done. The Board asked that the existing groups continue their work (with the Board’s enthusiastic support) until and while a review of committees can take place.
We are pleased to announce the new HathiTrust Resources and Guides  page, where we bring together overviews, instructional materials, and guides created by HathiTrust partner libraries, the Communications Working Group, and beyond. Materials posted on the page include reusable handouts, a detailed guide to using HathiTrust, lively blogs and dynamic videos. Please use, repurpose, and enjoy!
Have you created HathiTrust user guides or instructional materials? We encourage you to submit them to email@example.com .
It is now possible to embed HathiTrust volumes in web pages. Code snippets to do this can be found at http://www.hathitrust.org/embed .
Staff at the University of Michigan completed development of the first iteration of tools to help depositors create and validate content packages prior to submission to HathiTrust. The tools will be made available in early June to several partner institutions that are working on ingest of locally-digitized materials.
HathiTrust ingested approximately 150,000 additional public domain volumes from Harvard University Library.
As noted in Top News, the Communications Working Group released a new Web page  featuring HathiTrust instructional materials from across the partnership, including guides developed for public services use. In addition, the group submitted a briefing to the new Board of Governors with recommendations for carrying out communications activities in the future. The working group also launched a Pinterest account  for HathiTrust.
The User Experience Advisory Group focused its attention on a project being undertaken by University of Michigan staff to redesign the HathiTrust home page (www.hathitrust.org). The group will begin consulting regularly on this project in June.
The table below contains a summary of the issues received by the User Support Working Group in April.

Staff at California Digital Library (CDL) refined the code for loading bibliographic records into Zephir (the new bibliographic management system) and reloaded all HathiTrust records in the test environment. Work continued to code a process to sync rights information in Zephir with the HathiTrust rights database. The CDL team is developing documentation and guidelines for submitting bibliographic records to Zephir, and documentation of reports to be provided to institutions when records are loaded.
University of Michigan staff continued work on modifications to the HathiTrust PageTurner to display JATS XML. Staff began development of wireframes for the Dashboard module and are close to the completion of a specification for mapping JATS metadata elements to MARC fields to create analytic records for journal articles.
Who should attend? The HTRC UnCamp is targeted to the digital humanities tool developers, researchers and librarians of HathiTrust member institutions, and graduate students. Attendance will be capped at 60 participants, so plan to register early!
Travel funds and Registration. HTRC anticipates funding a small number of travel grants that can be used by an attendee to bring along a graduate student or for a HathiTrust member librarian/technologist to bring along a researcher from their organization who is interested in engaging with our research center. The Uncamp will have a minimal registration fee so as to make the Uncamp as affordable as possible for you to attend.
All of the data collection for English language volumes was completed in May, including double-review of subsets of volumes for quality assurance. Review of volumes in the grant’s final 1,000-volume sample, which includes volumes from 6 major non-Roman languages (Chinese, Japanese, Korean, Arabic, Cyrillic and Hebrew), is still in progress. At the end of May, staff had reviewed 77,115 of the total 95,086 pages sampled for review. Data collection is expected to be complete in mid-June.
Work in June will focus on analysis of the collected data, as well as research, development, and data collection for use case studies, which will comprise the final portion of the grant. Staff will also undertake a specialized study of errors in digitized illustrations to try to more accurately describe the types of errors that are observed and their impact on use.
Current findings of the project will be presented at the ALA Annual Meeting in June 2012. The project website  is being updated with a new graphic design; further initial findings  will be forthcoming. Please see the website for details on the volumes samples, error models, and other grant activities.
Staff at the University of Michigan made minor changes to the Data API and the Data API’s key service and Web client to better manage user privileges. A Data API security monitoring and reporting script was also deployed that runs on a daily basis.
Michigan staff undertook work to improve indexing and searching of CJK languages (a discussion of the issues is available on the large-scale search blog ). All 10+ million volumes are being re-indexed using the new CJKBigramFilter available in Solr 3.6, and a custom filter that will create a separate unigram index of Han characters (to support queries consisting of a single Han character). Staff revised the Solr indexing schema to eliminate unused fields and filters and to take advantage of upgraded Solr 3.6 filters. Staff also made changes in development to the full-text search and “search within a book” Web applications in preparation for the improved CJK indexing. Testing and production release of the application enhancements and newly-created index are anticipated in early June.
Staff at Michigan downloaded and began to index the INEX Book Track  “Prove It” task corpus to use as a testbed to investigate various relevance ranking issues in HathiTrust full-text search.
Staff at California Digital Library (CDL) completed development of fast lookup data structures in the language-sensitive dictionary that will support a spelling-suggestion feature in full-text search (last reported on in the Update on February Activities ). Staff used probabilistic techniques to fit the massive dictionary into RAM, allowing very fast lookup of bigram and unigram data. Staff also ported code from the CDL-developed XTF system that ranks spelling suggestions to the new structure, though the code is not yet fully functional. Next steps include modifying the ranking algorithm to take advantage of data from the language-sensitive dictionary, and evaluating and revising the algorithm to produce quality suggestions.
Staff at Michigan deployed fixes to the code that allows users to embed PageTurner views in Web pages using an iframe. Staff also added improved wording and an explanatory link to the PageTurner interface, recommended by the UX Advisory group in April, to clarify when full-PDF download of volumes in HathiTrust is or is not available.
Michigan staff completed the steps necessary to retire all storage that was scheduled for replacement in 2012. Staff had completed the installation of replacement and additional storage at the Michigan and Indiana sites in March.
HathiTrust’s VuFind-based bibliographic catalog was successfully moved from University of Michigan Library Web hosting infrastructure to HathiTrust’s Web hosting infrastructure. This completes a migration project that also involved HathiTrust’s Drupal-based informational website and will greatly simplify future Web development.
Full-text search in HathiTrust was unavailable on Wednesday, May 9 from 6:00-8:30am EDT due to a problem with an index server. Shibboleth authentication to HathiTrust was unavailable on Monday, May 21 from 9:23-9:28am EDT due to a problem with a helper service required by Shibboleth.
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 firstname.lastname@example.org .
