Fortunately not another conventional font catalogue, TDR instead devotes more space to the minutiae of typography, complete with diagrams and examples. This material is usually covered only in brief glossaries, so TDR's meticulous coverage is exceptional. (For a detailed account of typographic history, see Daniel Updike's Printing Types and Lewis Blackwell's 20th-Century Type; in both cases, the first and second editions are superior to the third.)
