Twitch. Grumble. Groan.

Books that propose to teach their readers how to write good research papers (or write anything, really) ought themselves to be properly edited. I understand that the most conscientious writers and copy editors will occasionally miss a typo, but the errors shouldn't be so consistent as to draw my attention away from the author's efforts to teach me better writing.

(It would make me very happy if all books were properly edited, really, but a book on better writing? Come on.)
