About *Surveying the Landscape* --------------------- This white paper analyzes the current landscape of use and usability studies conducted for digital libraries, focusing on three core areas identified at the 2014 Digital Library Federation forum: - Making usability studies more accessible to librarians (“usability studies”) - Tracking the return on investment for digital libraries (“return on investment”) - Understanding the reuse of digital library materials (“content reuse”) This paper identifies the strengths and gaps in the current literature in each of these three areas and makes recommendations for next steps toward the development of best practices. This paper was authored by the DLF AIG User Studies Working Group, one of four DLF AIG working groups formed following the 2014 DLF forum to develop best practices centered around assessment of digital libraries. The other working groups are focused on analytics, cost, and citations.
