This huge concordance will be the delight of any student of the Vulgate (this concordance is based on the Clementine version). This is an exhaustive concordance. No, it does not give every occurrence of "et", "in", "est", "ad", (like Strong's does in English) and other common words that occur too frequently to list but it does do a very good job of listing all the occurrences of most words. I have checked it against a modern electronic search program of the Vulgate and this one gets it right every time. The facsimile came out pretty well considering the age of the original copy.
