A posting on the Accordance blog indicates all the articles on St. Patrick in Accordance. I thought I would do a check in Logos to see what I could find. I have the Gold library and some PBBs, so this list probably is not complete, but here's what I came up with:
- An article in Who's Who in Christian History - This resource is available in many of the Logos libraries
- A Dictionary of Early Christian Biography - A substantial article in a free PBB you can download here.
- A number of references in Philip Schaff's History of the Christian Church - This is a free PBB you can download here.
- The "Confession of St. Patrick" (his autobiography) along with the "Breast-Plate of St. Patrick" and the "Shield of St. Patrick" - This is a free PBB you can download here.
- The Encyclopedia of Christianity - I only have the first 3 vols, but I have to believe that the recently released vol. 4 must have an article on Patrick.
- The Oxford Dictionary of the Christian Church - I don't have this one either, but I'm sure you'll find Patrick here too.
- Still want more? There's always Wikipedia!
