specialist work of writing on a single subject or an aspect of a subject
A monograph is a specialist work of writing (in contrast to reference works) or exhibition on a single subject or an aspect of a subject, often by a single author or artist, and usually on a scholarly subject.
In library cataloging, monograph has a broader meaning, that of a nonserial publication complete in one volume (book) or a definite number of volumes. Thus it differs from a serial publication such as a magazine, journal, or newspaper. In this context only, books such as novels are monographs.
