In the following two columns you will find a set of weblinks that will take you directly to the library's book catalog, ECCO. These searches are a little fuzzy (clicking on the link for the Gospel of John will also bring up books on the Epistles of John, etc.). Some of the books do not have weblinks, as we have no items in the collection that are specifically about that book. However, the majority of those texts are from the Apocrypha, which are oftentimes discussed together in one-volume commentaries, found via this link.
The library also owns several ebook commentaries. The three most useful sets are the Hermeneia series from Fortress, the Anchor Yale Bible Commentaries from Yale and the Wisdom Commentary series from Liturgical Press.
