The title "Who's Who" is in the public domain, and thousands of Who's Who compilations of varying scope and quality (and similar publications without the words "Who's Who") have been published by various authors and publishers. Many such publications can be described as Who's Who scams; they list any people likely to buy the book, or to pay for inclusion, with no criterion of genuine notability. In some cases the publisher also sells its list of biographees, optionally broken down by profession, sex, political affiliation or religion, to direct mail marketers.[1]
