Authors write books and work with written language, but although the job title is often associated with fiction, the work of writers is much broader than that. Authors are often divided into categories according to the type of work in question and the job title is even narrowed down, i.e., poet, novelist, screenwriter or playwright.
A distinction can be made, for example, between those who write fiction on the one hand; novels, short stories, poems or plays, and on the other hand authors who write on a specific subject within more specialized fields such as scholarly works or textbooks.
Most authors work independently and do not have a permanent employer, although they often work in collaboration with book publishers. Authors with a good command of languages and culture also often work as translators.
