Brown-Driver-Briggs Hebrew Lexicon

From BibleWiki

Francis Brown, R. Driver, and Charles Briggs spent over twenty years researching, writing, and preparing The Brown-Driver-Briggs Hebrew and English Lexicon, one of the most comprehensive Hebrew lexicons available (and usefully now in the public domain). It was based upon the easlier work of Wilhelm Gesenius, the "father of modern Hebrew lexicography".
