The current issue of the magazine 02138 reveals how some of Harvard’s top professors actually produce their books: They do it “with the help of a small army of student assistants who research, edit, and sometimes even write material for which they are never credited.”

These ghost writers are paid $11.50 an hour, says the magazine, which points out that if Harvard students handed in term papers written by somebody else, they would be expelled. It appears this rule doesn’t apply to their professors.
