Ithaka S+R has released the Ithaka S+R US Faculty Survey 2015 .
Here's an excerpt:
Ithaka S+R's survey of US faculty members has been fielded regularly since 2000. This project provides a periodic snapshot of practices and perceptions related to scholarly communications and information usage. The scholar-centric nature of the questionnaire ensures that potential changes in research and teaching inform our thinking, not only about academic libraries and scholarly publishing, but about changes in the educational enterprise more broadly.
