Abstract
This special issue is the fourth devoted to Open Educational Resources (OER) and the third to be drawn from papers presented at the main annual UK-based OER conference. For this special issue, the editors selected papers from the OER13 conference, held in Nottingham in March 2013. The main conference themes were Evidence, Experiences and Expectations, and the chosen papers exemplified some of the ways in which OER can link communities both inside and beyond Higher Education.
