Deuterocanon

Here are my favorites, with varying prices and densities but this list should give you an excellent start to find ones you like:

- Sacra Pagina

- Berit Olam

- Catholic Commentary on Sacred Scripture

- Catholic Commentary on Holy Scripture

- Paideia Commentaries on the NT

- Catena Aurea

- Ancient Christian Commentary on Scripture

- The Great Commentary of Cornelius à Lapide

- Hermeneia

Also some Bibles with good commentary in them:

- Navarre Bible

- Ignatius Catholic Study Bible

- Little Rock Catholic Study Bible

Happy hunting!

As you're discovering, there isn't much out there on the Deuterocanonicals.

The Anchor/Yales are often your best bet. Hermeneia has a couple volumes (2Macc, Judith); the Cambridge Bible for Schools & Colleges has a few older, more succinct volumes (1Macc, Sirach, Wisdom) --which have the advantage of being cheap.

The UBS Handbooks, while not commentaries, are very useful if you want exegetical insight (focuses on lexical & cultural meaning of words/phrases). The Deuterocanon is covered in six volumes.

For background/intro, Sheffield Academic has published I think 4 useful "Handbook" volumes in Logos covering most of the Deuterocanon. Daniel J Harrington S.J. published a ~200 pg Introduction to the Apocrypha that I found in my library (!).

Among the Catholic publications, the Collegeville/New Collegeville volumes are lightweight, and rarely worth consulting IMHO. The Navarre (early 21st-century) and Haydock (mid 19th-century) "commentaries" are sound, each in their own way, but are really just Study Bible notes without the Bible text. Orchard's One-Volume Catholic Commentary (mid 20th-century) is solid, but necessarily rather succinct.

A few other single-volume commentaries are available in Logos which cover the Deuterocanonicals: Eerdmans Commentary on the Bible (2003) covers the "Apocrypha" in ~160 pgs.; Harper's Bible Commentary (1988 ed.) covers the same scope in ~180 pgs. Gore's "New Commentary" (1928) covers the same scope in ~150 pgs.

In more thorough works: R. H. Charles' ~700 pg. Commentary on the Apocrypha of the Old Testament is available in Logos as a stand-alone volume (dirt cheap). The ~700 pg. volume on The Apocrypha of the Old Testament from Lange's commentary is also available very cheap as a stand-alone volume (no guarantees on the theological soundness of these...). Also, the New Interpreter's Bible contains the Deuterocanon spread across several volumes, though that appears to be available only as a complete set.

Some of these older works are included in the collection: Classic Commentaries and Studies on the Biblical Apocrypha / Deuterocanon (42 vols.).

Not a commentary, but perhaps a helpful starting point to open up further avenues for exploration would be Bergsma and Pitre's superb Catholic Introduction to the Bible: Old Testament (still on pre-pub...). Each book has roughly 20 pages of coverage, with attention to reception history and use in the liturgy that I think are particularly helpful.

You might also find some helpful content by digging around on Dr. Mark Giszczak's blog: CatholicBibleStudent.com. He spends a good deal of time working on Wisdom literature and has a number of bibliographies of commentaries for some of the deuterocanonical books.

The unfortunately titled ACCS volume on (most of) the Deuterocanon is handy, though perhaps chiefly for different uses than you have in mind.
