His prize-winning biography contains a full list of Perec's works.  Unfortunately the first edition (1993) published in Australia contained a rather unfortunate binding error.  About three-quarters of the way through, a whole section was reinserted into the book.  This made the rest of the book rather unreadable.  The second edition (1995) has hopefully corrected this.
