ABSTRACTTemporary exhibitions are a type of cultural activity that art museums have been organising for decades. As their name indicates, they have traditionally been short-lived events, something that began to change with the arrival of Internet. The design of virtual, online versions of temporary exhibitions and their availability to Internet users means that the truth of the adjective 'temporary' has become questionable. This article proposes a model of analysis and analyses their chief features, charting the types of online exhibitions that exist.KEYWORDS: Online exhibitionsInternetICTcultural disseminationtemporary exhibitionsmuseums Disclosure statementNo potential conflict of interest was reported by the authors.Notes on contributorsSantos M.
