What is an author bio / curriculum vitae (CV) / resume?
A curriculum vitae, or CV, is a brief description of you, your qualifications, and accomplishments – normally in this context in relation to writing (any previous publications, or awards, etc.), but in the case of nonfiction proposals may also include relevant experience that qualifies you to write on the subject. May also be referred to as a resume.
Author bio may be similar, depending on context, but if the bio is itself intended for publication (particularly in magazines) it may be broader in scope, describing your life and history more generally.
