I added two new links today on the left side bar. The first is a link to Bibla Clerus which is an online scripture commentary resource put out by the Congregation for the Clergy in Rome. You can search for chapter and verse and then get Church Father commentary for each one. It is extremely extensive.
The second is a link to the Haydock Bible Commentary, compiled and published in 1859 by Fr. Haydock. The online version isn't searchable but there are links to each book and then you scoll to where you want to go. Its not hard.
