International Standard Bible Encyclopedia

The International Standard Bible Encyclopedia (1915) is a public domain Biblical encyclopedia. This encyclopedia was published by Wm. B. Eerdmans Publishing Co. Hailed for its authoritative explanations of every significant word, person, and place in the Bible and Apocrypha, it is a standard by which other Biblical encyclopedias are measured. In contains articles by nearly 200 scholars about archaeological discoveries, the language and literature of Bible lands, customs, family life, occupations, and the historical and religious environments of Bible people.

In addition there is a completely overhauled, modern version which should not be confused with the public domain 1915 edition that can be found freely available at various sites.
