Delivering access and use of the HathiTrust Digital Library

D2I partnered with the University of Illinois and the HathiTrust Digital Library to create the HathiTrust Research Center (HTRC) to enable access to and computational non-consumptive use of the HathiTrust Digital Library. The sheer size of the library (over 14 million volumes and over 5 billion pages) demands innovative thinking about the architecture and the optimization at all levels of the software infrastructure from hardware to applications.

Our research and development focuses on reducing reads, intelligent caching, and delivering maximum cycles at minimal costs, providing secured environments for copyrighted materials.

Tools that are being implemented for humanities and social sciences research include structural, semantic and/or syntactic element extraction and analysis, metadata processing, and analyses that allow to trace changes in usage and meaning over time, such as parts of speech and word counts.
