Rick, the 1966 Jerusalem Bible has large margins - being one of the largest, heaviest Bibles. The Knox, at least the late 40s to mid-50s editions have pretty decent margins. A large, but beautifully illustrated Bible with good margins is the 1953 Catholic Action Bible. Gorgeous. Which physical size are you looking for? If you do not mind a large, “family” size Bible, you have more choices, such as the Jerusalem, and Family-sized Catholic Bibles. Margins and physical size are one thing, but the text and its translation are quite another.
The Douay-Rheims is classic. The Knox is based on the Clementine Vulgate and is praised - Bishop Sheen’s favorite translation. It’s notes are thought provoking. The real sleepers are the 1941-1969 Confraternity Bibles. A beautiful rendition of the NT, with varying degrees of the Douay Old Testament combined with the OT translation that became the NAB. Excellent, confidence-inspiring notes and intros.
The downside to the Jerusalem, NAB and NAB/RE are that their translations are modern and less “Catholic.” In the NAB, Mary is not full of grace, for example, but Stephen is. Saint Paul forgave sins in the “presence” of Christ, rather than in the “person” of Christ. Things like that.
You can buy a new Bible, but I much prefer old, barely used Bibles. I have them from 1914 to 1970. I got an excellent leather-bound 1949 Confraternity Bible for $2! A lot of choice out there, but I particularly dislike the modernist notes in the NAB and NAB/RE. They suggest, for example, that Luke either made up Mary’s Magnificat, or copied it from some other Hebrew source.
Unacceptable to me.
