This should be presented as a condensation of material available in Wyckoff and your other sources. It's effective and useful for that purpose. It doesn't break new ground, and while it doesn't pretend to, it would be more useful if it were presented as an online introduction to the monograph itself, for which it would then serve as a useful model for future introducers of other monographs. That allows the reader to understand that the practical task is judging the reliability of the monograph, which you have not actually undertaken to determine for yourself.
