The collection of great Christian writers, which totals 5,103 volumes, including many personal works, represents the subject areas of literature, theology, travel, biography, science, hymnody, history and humor.
Religion is the largest category in the collection.
The Spurgeon Collection is regarded as the world's finest library of Puritan literature in existence. Dr. John Priest Greene, President of the College, Dr. J.T.M. Johnson, John E. Franklin, and Dr. J.E. Cook were instrumental in acquiring the collection. Dr. Thirtle supervised the packing of the books into 38 canvas-lined wooden crates and arranged for transportation, insurance and customs. Dr. Thirtle corresponded almost daily with the purchasers. His letters are still part of the Spurgeon records.
