A monograph is a short treatise on a specific subject. A monograph and a treatise serve the same purpose with the difference that a monograph is an attempt on a limited scale. Very often, a monograph may be brought out as a part of a series.“A separate treatise on a single subject or class of subjects, or on one person, usually detailed in treatment but not extensive in scope and often containing bibliographies. Frequently published in series. In cataloguing, any publication which is not a Serial”. Harrods Librarian Glossary and Reference Book.
