His books on drawing are the most lauded since he's a fairly good introductory teacher, but feel free to read all of it.

In terms of most useful books, though, you'd go from the drawing books straight to more draftsmanship stuff like Scott Robertson, then to something like Alla Prima 2.

I mean, of all the crap that you could read on illustration demoing and tutorials, Andrew Loomis' work is in no way particularly detrimental unless you're an incredibly impressionable and inflexible human being. So take it easy.

Do you know if he has a book about rendering?

Fun With a Pencil is his first book and it shows, it's not a great book. However, Eye of the Painter and Head & Heads are pretty good and are well worth reading.
