Bible dictionaries are organized alphabetically like encyclopedias.  They have articles on thousands of topics. Useful sources are often listed at the end of articles.

Concordances list every word in the Bible in context. 

Commentaries interpret passages in Scripture verse by verse and are arranged in Biblical order.
