Book excerpt: Abraham Lincoln's Legacy of Laughter, a substantial revision of P. M. Zall's 1982 classic, Abe Lincoln Laughing, consists of stories, jokes, and anecdotes on a wide range of topics by and about Abraham Lincoln before and after he became president. Establishing which tales are authentic and which are frauds and delusions, Abraham Lincoln's Legacy of Laughter includes stories derived from Lincoln's writings and speeches; writings by others up to April 1865; post-Civil War writings by those who knew him; and writings by others about Lincoln in later decades, including a sample from the twentieth century. Within each group, entries are arranged in the order they appeared in print. The volume contains notes, a bibliography, an index of the entries by section, and a subject index.
