Are the positions in Fred Reinfeld's "1001 Brilliant Ways to Checkmate"
based on real games or are they composed?

The Checkmate Challenge at http://www.testyourchess.com has 288 checkmate
problems based on real games by masters and others, and I'm wondering if
something similar (i.e. based on real games) exists in book form or
electronically (eg PGN or ChessBase format).

Reinfeld used game positions for his two "1001" books, as far as they can be
verified, many from famous international contests of the twentieth and
nineteenth centuries. But since Reinfeld never cites game sources, the game
scores and players from many of the positions are, I suppose, lost forever in
the mists of 1920s-1950's New York master and amateur chess.
