Else, P. (2009) The Value of Play. London: Bloomsbury.

Gives a thorough grounding on play from a playworker’s perspective, valuing play for its own sake rather than as a vehicle for learning. Free play, choice and learner-centred processes are inherent in FS. This different perspective on play is crucial and often less acknowledged within traditional education training.
