The list author says: "When challenged to present a substantive yet succinct account of their subject matter in less than 150 pages, a number of scholars have written remarkable short books. Some of these books were originally lecture series and, thus, maximize the clarity of presentation. Others represent syntheses or summaries of larger works of scholarship. And, in some cases, authors have expanded what was basically an article-length work into a tidy monograph. I don’t include in this list books that collect independent articles."
