What is the book’s subject? What is its scope–limited by era, by topic, or some other factor?
Explain the book’s argument, discuss the author’s method (what sources used? how well were they used?
See below, for the questions of methods of sources for each book), and critique the book’s argument–how convincing? Other explanations that the author didn’t consider? Other sources the author might have used? How useful for historians, students of history, or history buffs?
