Collection (publishing)
In the field of book publishing, a collection or, more precisely, editorial collection (French: collection éditoriale; Spanish: colección editorial; Italian: collana editoriale; Portuguese: coleção de livros, lit. 'collection of books'), is a set of books published by the same publisher, usually written by various authors, each book with its own title, but all grouped under the same collective title. The collective title is the title of the collection and must be mentioned on each book.
