"Innumerable"? That's so true. Someone once said that there has been a book published on the ACW every day since the war ended.
If you want to read about the war from the viewpoint of the men who fought it, you can't do better than this:

Originally published in the 1880s, and written by the generals and privates who fought the war, it gives hundreds of first-had accounts by people who were there. The price is great too. There are four volumes, and you can get all four for under $30. Ignore the listings for "Volumes 5 and 6" - those were compiled later by a historian. They may be good but they're not the original work.
The Time-Life series, as already mentioned, is phenomenal, but is also quite long. Of course anything worth reading is going to be detailed and possibly boring. The Shelby Foote series is a great overview, as is Ken Burns' 1990 documentary film:
