There are six sections:Elementary Principles of Literary ConstructionConventions Governing Punctuation, Capitalization, Typography, and FootnotesCharacteristics of Bad WritingWords Often MisusedWords Often MispronouncedProofreaders' MarksApparently Lasch's frustration with students went beyond just their writing skills. "I keep simplifying my course in 20th century American history, but the students keep getting dumber faster than I can simplify it," Lasch wrote in a letter to his father. "Every year the illiteracy gets worse."The current book was published after the author's death and includes an introduction by Stewart Weaver. The introduction is disproportionately long, taking up 42 of 121 pages.
