While a handy little reference and informative, I do have some reservations about the format; Basically, it is ordered alphabetically by Saint name, and there is no other way to look up a particular saint. Say you had been to a remote area and visited some relic or other but could not remember the saint's name: there is no index or any cross reference or any other way to look that up in this tome. That is a severe detriment. Additionally, I would have liked to see it more as a DK or Phaidon book, more photos and illustrations, set up more like the encyclopedia it touts itself to be. All of that not with standing, it was an interesting read to sit down and consume cover to cover with a wealth of information for the casual connoisseur.
