Book excerpt: "Herblock's History" is an article written by Harry L. Katz that was originally published in the October 2000 issue of "The Library of Congress Information Bulletin." The U.S. Library of Congress, based in Washington, D.C., presents the article online. Katz provides a biographical sketch of the American political cartoonist and journalist Herbert Block (1909-2001), who was known as Herblock. Block worked as a cartoonist for "The Washington Post" for more than 50 years, and his cartoons were syndicated throughout the United States. Katz highlights an exhibition of Block's cartoons, that was on display at the U.S. Library of Congress from October 2000. Images of selected cartoons by Block are available online.
