JSTOR, a not-for-profit digital archive of scholarly journals, books, and other content, recently launched a new Labs team that partners with publishers, libraries and labs to develop new ways of organizing and navigating research literature in a digital environment. In this talk, Alex Humphreys, Director of JSTOR Labs, discusses the development of a new JSTOR project focused on Sustainability. The project, which incorporates scholarly and policy literature from the environmental humanities and social sciences, is being designed with guidance from scholars and subject librarians across disciplines to help students and scholars better understand and navigate the growing corpus of interdisciplinary research in this field. The talk will include a discussion of the challenges in building a library of scholarly materials on Sustainability, a demonstration of some of the functionality that has been developed for the Sustainability project in collaboration with scholars, including a semantic index and a collection of topic pages, and an overview of the research and development methodology that we use in developing new functionality for JSTOR—a process that has enabled us to develop and test new features in as little as a week’s time. The talk may be of especial interest to conference attendees who teach undergraduate students, and to graduate students and early-stage scholars who are considering alternative-academic careers in publishing or technology.
