Writers are either classified as authors or technical writers. Writers and authors write books, magazine articles, online publications, company newsletters, and numerous other materials. Their work is considered either fiction or nonfiction. Writers are usually identified as novelists, playwrights, biographers, screenwriters, and textbook writers. Certain freelance writers are sometimes sponsored to write a script while others are contracted to write a book after a draft or an outline they submitted to a publisher is accepted. Writers sometimes submit materials for song writers or scriptwriters.
