This book is a shamefully shoddy production that shows no evidence of there having been an editor, or even a literate author. Extraneous words are left in. Other words are missing. There are many typos and misspellings. Apparently no proofreading at all was done. The subject, Dr. Nibley, deserved better. For an example of how it should have been done, see the superb book " Sergeant Nibley, PhD ".
