Many authors publish books under “pseudonyms” or pen names. An author might do this to preserve his privacy, as a marketing strategy or for other reasons. Stephen King has written under several pseudonyms during his career, including Richard Bachman and John Swithen. Thriller writer Dan Brown co-authored a humor book entitled "187 Men to Avoid: A Guide for the Romantically Frustrated Woman" under the pen name Danielle Brown. Using a pseudonym allows an author to write in other genres without being stereotyped.
