Query: Full of mistakes

It appears that some fool edited the cautionary examples for correctness. (p. 34) The grammar is poor ("verboten" as a noun? (p. 85)), and the usage is non-standard (Commas are "trundled out"? (p.37)). Some passages are self-contradictory ("With Adjectives, p. 37).This book is not a total disaster, but I can hardly recommend it.
