Anchor Yale Bible Dictionary
The Anchor Yale Bible Dictionary originally published in six volumes, 7,200-pages, features more than 6,000 entries from 800 leading international scholars. Covering numerous Biblical subjects, the Anchor Yale Bible Dictionary is a premier resource for students of the Bible. In his review of the Anchor Yale Bible Dictionary, Gene M. Tucker, of Emory University, describes it as “a gold mine of information on and interpretation of an extremely wide range of topics concerning the Bible and its environment, from AARON to ZUZIM.” (The contents of the Anchor Yale Bible Dictionary are identical to the Anchor Bible Dictionary. The name of the product has changed because the copyright for this resource was transferred from Doubleday to Yale University.)
