On p. 5 of the Spring issue, Klara Wojtkowska should have been credited as having done a significant portion of the translation and editing of the "Open Letter to the Parties" from Polish to English.
One error of fact and two typos crept into the article regarding Jill Lepore in the Spring issue. On p. 81, Lepore is incorrectly described as having been in the Army ROTC. She was in the Air Force ROT. On p. 84, the dates for Jared Sparks are 1827 and 1837, not 1927 and 1937.
All corrections have been made online. [End Page 126]
