Sometimes an author does not want to use his or her real name in the published form of whatever it is that he or she has written. A pen name or pseudonym is a fake name that is used to conceal the real identity of the author, while still allowing the reader to associate the written material (books or whatever) with a specific person. Even some very famous and well loved authors have done this; for example, the real name of Mark Twain was Samuel Clemens. And on this web-site, and many other web-sites, it is quite common for people to use pseudonyms. My own name, for example, is not really blobbert.
