Others have pointed out the existence of the five volume and single volume Dictionary of the Bible edited by James Hastings in Community Pricing. Note that the single volume is not a condensed version of the five volume work, but is a separate effort.
I found the following in a review written in 1963 concerning the release of the Interpreter's Dictionary of the Bible.
"The editor and his associates are to be commended for having produced
this
dictionary. The print is clear and sharp and is easy to read; the
numerous illustrations
have an educational value and generally add to the beauty of the page.
In the
middle of each volume are eight colored plates, but they have no
relation to
the adjacent pages. This up-to-date work should be in the pastor's
study, but
if he has Hastings' four-volume Dictionary of the Bible or the
Encyclopaedia
Biblica, he should not discard them: they represent a type of
scholarship
that may never be repeated. And furthermore there should still remain
room on
his shelf for a one-volume dictionary of the Bible.

Dr. Gehman was William Henry Greene Professor of Old Testament
Literature at Princeton Theological Seminary for years and a teacher of Bruce Metzger. When he states that the five volume (he refers to it as the four volume) dictionary, while dated at that time, 'represent(s) a type of scholarship that may never be repeated' that is a strong endorsement.
