While I was one of three Faculty Fellows with the BCcampus Open Textbook program, we conducted a survey of faculty in BC and beyond, focusing on their use of and attitudes towards Open Educational Resources and Open Textbooks. We got over 70 complete responses from faculty at various institutions, most of them from teaching institutions rather than research institutions.
We published a white paper about the survey, which was released in January of 2016. You can read a brief summary of the report here.
Here is a link to the PDF of the full report.
We also presented the results of this survey at two conferences before the white paper was finished:
The BCcampus Open Textbook Summit, May 2015, Vancouver, BC. Here are the slides from that presentation.
The 2015 Open Education Conference, November 2015, Vancouver, BC. Here are the slides from that presentation.
