Over 34,000 pages in its original 56 volume printing, the Biblical Illustrator is a massive compilation of treatments on 10,000 passages of Scripture. It is arranged in commentary form for ease of use in personal study and devotion, as well as sermon preparation.
Most of the content of this commentary is illustrative in nature, and includes from hundreds of famous authors of the day such as Dwight L. Moody, Charles Spurgeon, J. C. Ryle, Charles Hodge, Alexander MacLaren, Adam Clark, Matthew Henry, and many more. The collection also includes lesser known authors published in periodicles and smaller publications popular in that ara. Unlike modern publishers, Exell was apparently not under any pressure to consolidate the number of pages.
