A monograph is a specialist written work or exhibition on one subject or one aspect of a usually scholarly subject, often by a single author or artist. Although a monograph can be created by two or more individuals, its text remains a coherent whole and it keeps being an in-depth academic work that presents original research, analysis, and arguments. As a focused, in-depth and specialised written work in which one or more authors develop a uniform and continuous argument or analysis over the course of the book, a monograph is essentially different from an edited collection of articles. In an edited collection, a number of original and separate scholarly contributions by different authors are edited and compiled into one book by one or more academic editors.
