The principle of parallelism, of course, is violated daily and wantonly wherever words get pushed together. In fact, the 1993 Manual's back-cover list botched things on an even grander scale. The item already mentioned—the verb phrase "Incorporates recent changes in style, usage, and in computer technology"—clashed with the list's other four items, all of which were noun phrases:

• Many more examples in every chapter
• An improved, easier-to-use section on documentation
• A rewritten chapter on rights and permissions
• New material on names and terms, quotations, foreign languages

(We might wonder, too, why the closure-imparting conjunction and was omitted from the fourth bulleted phrase.)
