"A best-seller was a book which somehow sold well because it was selling well"

This quote by Daniel J. Boorstin is a commentary on the phenomenon of best-sellers. It suggests that the success of a book is often identified by its own success. In other words, a book can become a best-seller merely since it is currently selling well. This is a reflection of the power of word-of-mouth and the influence of popular opinion. It implies that the success of a book is frequently identified by its own popularity, instead of its quality or material. This quote also recommends that the success of a book is frequently determined by its own momentum, as it can become a best-seller simply due to the fact that it is already selling well. This is a commentary on the power of the general public and the impact of popular opinion. It implies that the success of a book is frequently identified by its own success, rather than its quality or material.
