They're not books as such, they're collections of articles that were previously published in Furniture & Cabinetmaker.
That's not a criticism, they're some of the best writing on woodworking that I've ever read. Not only do they cover some topics that you just won't find anywhere else, they also give a real insight and appreciation for the painstaking care and meticulous approach that first quality work demands.
Get volume one, then start angling for more book tokens so you can get volumes two and three!
