"Who's Who in America" as published by Marquis Who's Who is a legitimate biographical directory that has been in existence since 1898, originally founded by Albert Nelson Marquis. It profiles individuals considered notable or influential in various fields such as science, business, law, education, medicine, and the arts

. However, the value and selection process of Marquis Who's Who are often viewed as subjective and more akin to a vanity publication. While inclusion in the directory itself is free, individuals are frequently encouraged to purchase expensive commemorative products like plaques, books, or expanded listings, which has led some to perceive it as a marketing strategy rather than a strict merit-based honor

. Moreover, the phrase "Who's Who" is in the public domain, so many other publishers use the name to create similar directories, some of which are outright scams. These scams often involve unsolicited emails or calls inviting people to be listed for a fee or to buy overpriced memorabilia, sometimes with attempts to steal personal or financial information. Therefore, while Marquis Who's Who itself is legitimate, one must be cautious of impersonators and scams using the "Who's Who" name

. In summary:

• Marquis Who's Who in America is a legitimate, longstanding directory with historical credibility

• Inclusion is free, but purchasing products is optional and costly, which can feel like a vanity scheme

• The selection process is not strictly rigorous, leading to questions about exclusivity

• Many scams use the "Who's Who" name to exploit people; vigilance is advised to avoid fraud

Thus, "Who's Who in America" by Marquis is legit, but its practical value and exclusivity are debatable, and one should beware of related scams.
