2008 June, Bruce Morrison, “The role of the self-access centre in the tertiary language learning process”, in System, volume 36, number 2, →DOI, page 123:This paper discusses the role of the self-access centre (SAC) in tertiary language learning and teaching, a role which has developed out of the changes that have occurred within the disciplines of Applied Linguistics and Education as well as from wider changes in technology and society itself. As the focus in language learning has moved, over the past thirty years, from the teacher to the learner, self-access language learning has emerged as a complement to the more traditional face-to-face learning model, with SACs now operating in many parts of the world.
