 Section 10.9 'Type Families' intro has external links to three papers,
 labelled

 [AssocDataTypes2005]
 [AssocTypeSyn2005]
 [TypeFamilies2008]

 The links point to http://www.cse.unsw.edu.au/~chak/papers/....html. I get
 Access Forbidden Error 403.

 Instead they could point to the microsoft research publications
 versions(?) (Each is co-authored by Chak and SPJ and others.) But beware
 some of those are draft versions.
