The term 'COLLECTED WORK' can be solved by the 7-letter word 'OMNIBUS'. An OMNIBUS is a collection of works, usually in the form of a book or series of books, that are compiled and published together. It typically contains a variety of works, such as short stories, essays, poems, or plays, all written by the same author or from the same time period. Omnibuses are often used to make a single work more accessible to readers, as they can contain a large amount of material in one volume.
