With some books on history i noticed that the author has reworked his PhD thesis into a book - now that's a long bummer by definition, If that is the case then that makes the book quite long to start with - (i think that's the right thing to do BTW). One example: The PhD thesis: "Political Protest and Dissent in the Khrushchev Era" by Robert Hornsby" (342 pages) the book would be "Protest, Reform and Repression in Khrushchev's Soviet Union" by Robert Hornsby (324 pages)
