Nikon D3200 by Simon Stafford

If you'd like a real printed book, the best I've seen so far is Simon Stafford's D3200 Guide. It's a smallish book perfect to take in your bag loaded with precise specifics about how to use the D3200. It's also got a few punch--out plasticised cards to keep in your wallet. It's much better than most of the guides I've seen which are mostly generic picture-taking guides with just a picture of one camera on the cover and in the title.
