This document summarizes the results of a large-scale survey of over 19,000 readers globally about how they discover and access scholarly content. The survey was supported by several academic publishers and aimed to provide data to publishers, libraries, and technology companies on the relative importance of different discovery channels. It finds that while publishers' websites and search engines are still dominant, libraries and library-linked discovery tools play an important role in many subject areas. The full report contains extensive breakdowns of the results by demographics, disciplines, and other categories.
