Information sources that have been written by academics, experts or creative practitioners in a particular field or discipline, and published in books, conference publications and academic journal articles, can usually be considered scholarly.
They may report on original research, review books, films or productions, address current issues in the media, or examine events through the lenses of history and theory. They are your best source of information about topics such as fashion and dress history, film and cinematography, theatre productions and techniques and the role of costume design on stage and screen.
