Mark Allen purchased his first AP Stylebook 25 years ago this month and read it from beginning to end. He now juggles AP, the Chicago Manual of Style, APA style, a bit of MLA style, and several local style guides as a freelance copy editor. His personal style often involves a bow tie and sometimes includes a fedora. He is a member of the American Copy Editors Society executive board and teaches advanced copy editing through UC San Diego Extension. He is the owner of markallenediting.com.
