Glue and counter-sunk screws, with a dowel (I prefer a contrasting color) plug on top. Flush cut or even slightly protruding, whichever style you like. Looks great, can't fail, super easy. I've done all kinds of joinery, of course rabbets, dovetails, all that good stuff... is good. But y'know what else is good? A finished bookshelf holding a bunch of books!
