The Complete Book of Paint: a sourcebook of techniques, finishes, designs, and projects, by Lynne Robinson (Oversize HC, $3)
Those who know me, know enough to keep paint cans away from me.( I tend to paint more floor than I do walls, and it is usually only the walls that need painting.) I am not sure that this book helps careless people like me, but it certainly will help anyone else.
Look for this in the home improvement section.
