Great D&C Study Aids

You can get the back story on the people and history behind each section of the Doctrine and Covenants called Revelations in Context. On a cell phone, you find it under Library, then Church History. Here's a LINK for it for your computer. Since it's in the Gospel Library, you can directly link excerpts from it into your scriptures!

Another of my very favorite study aids is the excellent book, Who's Who in the Doctrine and Covenants,, by Susan Easton Black, which lists every single person who is mentioned in any revelation, and their back history. Sister Black has dug up so many interesting tidbits that you never get anywhere else.
