HathiTrust institutions approved bylaws put forward by the Board of Governors for voting in January. The bylaws are available at http://www.hathitrust.org/documents/hathitrust-bylaws-201302.pdf .
HathiTrust hosts a page of resources  including handouts and informational sheets created by the Communications Working Group, and links to information about HathiTrust that institutions have posted for their own constituencies. If you have posted resources about HathiTrust (including videos, library guides, etc.) that are not listed, please let us know (firstname.lastname@example.org ), and feel free to use and share those that are available.
HathiTrust hosted a conference call with members of several partner institutions that have been working with HathiTrust’s ingest tools , to discuss development options for the next iteration of the tools. A summary of the meeting, including next steps, is posted in a Google Group forum on HathiTrust Ingest . Individuals interested in issues surrounding ingest of locally-digitized content into HathiTrust are welcome to join. HathiTrust continued to respond to inquiries about the ingest tools and ingest of locally-digitized materials.
HathiTrust began ingest of new batches of volumes from the University of Florida, the University of Illinois, and the University of North Carolina at Chapel Hill. HathiTrust also loaded bibliographic records for new volumes from Columbia University and Penn State.
Working groups and committees in HathiTrust may have an operational or strategic focus. See http://www.hathitrust.org/working_groups  for more information.
The User Experience Advisory Group began to review elements of HathiTrust Web applications that were previously identified as in need of improvement and to review feature requests that have been submitted to the User Support Working Group.
A summary of issues received by the User Support Working Group is given in the table at the end of the update.
California Digital Library (CDL) continued to work with staff at the University of Michigan to test data exports from Zephir and to plan for the upcoming transition to Zephir for HathiTrust bibliographic metadata management. CDL staff made modifications to support rights determinations on bibliographic records that conform to the Resource Description and Access (RDA) standard. CDL is in the process of implementing a new backup strategy for Zephir to ensure the service will be accessible in the event of an outage. An updated timeline for the project is posted at http://www.hathitrust.org/htmms .
A summary of the determinations from HathiTrust copyright review activities in January is given below.
Public Domain Determinations
Public Domain Determinations
Staff at the University of Michigan met to discuss possible changes to the HathiTrust PageTurner, item-level search, and item-level search results to accommodate materials submitted via mPach. Staff began working with sample analytic MARC records and METS objects to determine the scope of anticipated changes. Staff also reviewed the mPach ingest process and discussed workflows for processing issue- and journal-level metadata.
Staff at Michigan continued to work on relevance ranking for full-text search results. Experiments performed in January found that some very short documents were being ranked too highly by Solr’s default ranking algorithm. Preliminary tests indicated that the issue may be resolved by using Solr’s new BM25, DFR and Information Based ranking settings. Experiments will continue in February.
Michigan staff received official relevance judgments for full-text search data submitted to the 2012 INEX Prove-IT Book Track  (see also the paper "Practical Relevance Ranking for 10 Million Books "). After evaluating the results, staff submitted new data using updated relevance judgments.
Staff at CDL made significant progress on a spelling suggestion feature for full-text search. Staff improved the relevance of results through the creation of a new dictionary of suggestions that uses a bigram index for an entire shard’s worth of documents (about 800,000 volumes). The HathiTrust full-text index is broken into “shards” in Solr’s search architecture. Staff also tuned the algorithm that provides suggestions and made significant changes to suggestion scoring parameters, significantly increasing the quality of results. CDL will now look toward deployment of the new feature.
Michigan staff made adjustments to the full-text search indexing process to better support experimental indexing runs and to synchronize data between the full-text search index and information in the HathiTrust print holdings  database.
HathiTrust completed the purchase of high-performance storage for full-text search. The new systems are expected to be received in late February for installation and testing.
HathiTrust began to implement application-level changes to support access to materials by designated representatives at partner institutions on behalf of users at those institutions who have print disabilities. Designated representatives will need to register and to access HathiTrust using their Shibboleth login from a fixed IP address. Further details on the service will be forthcoming.
HathiTrust completed stylistic changes to messages in mobile PageTurner that appear when special access to materials is granted (e.g., access to volumes that fall under Section 108 conditions or to users who have print disabilities).
HathiTrust completed projections for new and replacement storage needed for HathiTrust in 2013.
Staff at Michigan drafted implementation guidelines for a unified Web application framework for HathiTrust. The framework will simplify the execution of a redesign of the HathiTrust website, which is expected to be completed in April.
HathiTrust was unavailable from 5:00-5:40pm EST on Monday, January 21 due to an error in a software release.
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 email@example.com.
