Abstract
Twenty years ago, Donald Swanson coined the term ‘Undiscovered Public Knowledge’ to refer to the product of the synthesis of previous research. In the current climate, in a range of disciplines relevant to tourism research (e.g. policy, management, economics and psychology) there has been an increasing interest in the maximisation and re-use of previous research through a range of research synthesis approaches. This discussion paper considers three such approaches – systematic review, meta-analysis and meta-interpretation – and their actual and potential application in tourism research. The paper contends that the use of such approaches can assist in ensuring that the tourism research enterprise generates cumulative bodies of knowledge built on the full use and exploitation of previous research results.
