HTRC also works on outreach, education, and developing new interfaces and tools to enable scholarly research using its collections and infrastructure.

- 10. Non-Consumptive Research Paradigm • No action or set of actions on part of users, either acting alone or in cooperation with other users over duration of one or multiple sessions can result in sufficient information gathered from collection of copyrighted works to reassemble pages from collection. • Definition disallows collusion between users, or accumulation of material over time. Differentiates human researcher from proxy which is not a user. Users are human beings.

Editor's Notes
- #17: 18. 11. 2015
- #22: The Scholarly Commons component of HTRC involves librarians and informatics professionals at Indiana, Illinois, and other institutions collaborating to provide baseline education and research consultations to support researchers get their text data mining research off the ground Focus on improving the user eXperience through user requirements study: conducted seven interviews for the User Requirements Study, with plans to complete 15-20 interviews through Fall 2015 Outreach activities: In addition to the annual HTRC UnCamp outreach event, HTRC representatives gave more than 35 presentations or workshops in 7 countries this year. 6 workshops were taught at venues both local and national. Local workshops were presented at Illinois and Indiana. Conference workshops: HASTAC 2015, the Modern Language Association Annual Convention 2015, and the 2015 Joint Conference on Digital Libraries. 29 talks or lectures were presented at professional conferences across a number of disciplines, including: Supercomputing 2014, the 2015 Joint Conference on Digital Libraries (papers and a keynote address), and Digital Humanities 2015. 128 people from 24 institutions attended the HT/HTRC UnCamp held March 2015 in Ann Arbor, MI. Education activities: development of workshops in the spring of 2015 facilitated a burst of national and international workshop activity this summer. hope to deliver at Committee on Institutional Cooperation (CIC) libraries. The idea is to begin with the CIC institutions, gain feedback, refine the workshops, and then expand to the broader HT member library community.
- #23: IMLS Laura Bush 21st Century Librarian grant: Led by HTRC associate, Harriett Green, and along with librarians at Indiana University, Northwestern University, University of North Carolina at Chapel-Hill, Lafayette College, the HTRC, has just been awarded an Institute for Museum and Library Services Laura Bush 21st Century Librarian grant entitled, “Digging Deeper Reaching Further, Libraries Empowering Users to Mine the HathiTrust Digital Library Resources.” This project, with an award amount of $398,845, runs from October 1, 2015 to September 30, 2018 and is intended to develop a shared curriculum for use in academic libraries including a train-the-trainer series designed to assist librarians in getting started with the tools, services, and related research methodologies of the HTRC.
