John Bartlett (June 14, 1820 – December 3, 1905) was an American writer and publisher whose best known work, Bartlett's Familiar Quotations has been continually revised and reissued for a century after his death. The fourth edition of "Familiar Quotations" was published in 1863. The present, 5th edition, embodies the results of the later researches of its editors, besides the contributions of various friends, and includes many quotations which have long been waiting a favorable verdict on the all-important question of familiarity. A few changes have been made in the arrangement, and the citations from Shakespeare have been adapted to the principal modern editions.
