Book Notes: from nostalgia to history

Stuart Henderson's new book, Making the Scene, just out from University of Toronto Press, is a history of sixties Yorkville, the heart of the counter-culture scene of Toronto, now an expensive shopping-and-hotels neighbourhood.
The author is a York University post-doc (York is also in Toronto, but a million miles from Yorkville), hence, I'm guessing, youngish and a student of the sixties as history rather than a nostalgic memoirist.  Wonder how his aging doctoral supervisors handled the nostalgia/history nexus?
