The references are lacking if you are searching out something from another bible verse; this bible does not link you to witness scriptures as other study bibles. But it gives you thorough information concerning various topics like the flood, creation, etc; great for a person who actually wants to study to know and link scripture based on a topic. I enjoy it because it is a study tool for me along with other study bibles; always view other study bibles, you find you have much to learn every time you search the Holy book.
As others have stated, Christian Books has made putting my Theological Library together more then affordable. The Old Scofield Study Bible Classic Edition is invaluable with it's references dating back to 1917. The introduction on each of the pages of the Prophet or Apostle your reading are a great study aid in bringing more understanding of what your about to delve into.
