In reply to humptydumpty:
"Classics" is a small book, pocket sized and ideal to take on multi-pitch routes. Thus it is very much against the modern trend. The downside , of course, is that it has fewer routes, but if you're mainly interested in the 2* and 3* VD to VS, and are an occasional visitor, then it could be fine for you.
NW "Rock" and the competing Ground Up selective are much bigger books, too big, really, to take on multi-pitch routes (so you memorise the route, or photocopy the guide, or take a pic of it with a phone), but have many more routes.
