Don't forget the Collegeville Catholic Reference LibraryThe Collegeville Catholic Reference Library 2.0 is reference by
Catholic Resources for Logos Bible Software.
It not only contains the NAB (New American Bible) but also:
The New Dictionary of Sacramental Worship
The New Dictionary of Theology
Locked material on The Rule of St. Benedict, etc.
The commentary is extremely useful when synchronized in Libronix with the NAB, or indeed with any other translation you may have, but it is most useful in explaining the text-critical footnote material.
