A
thesis by publication, also known as an
essay thesis or an
article thesis, is a
doctoral dissertation that, as opposed to a coherent
monograph, is a collection of research articles with an introductory and a summary chapter. It comprises already-published journal articles, conference papers and book chapters, and occasional not yet published manuscripts. A thesis by publication is a form of
compilation thesis (a term used in Nordic countries). A less common form of compilation thesis is an
essay thesis, comprising previously unpublished independent
essays.
