The Treasury of Scripture Knowledge is a Bible cross-reference work published around 1830, by Samuel Bagster (1772-1851). His book consisted entirely of a book-length listing of cross-references, showing only the chapter and verse citations. It is about the size of a complete Bible and it is organized like a Bible. It has,

- 800,000 cross-references, listing verses that illustrate how words and phrases are used elsewhere in the Bible.
- Brief chapter summaries.
- Dates and other notes.

R. A. Torrey is often accredited as the author of the Treasury of Scripture Knowledge, but in reality he was less involved in the authorship and more involved in its promotion.
