One of my favorite old books was Brewing Classic European Beers at Home by Wheeler and Protz, that came out in 1999. Some sort of updated version of that, with suggested yeast strains, would get me to buy one.
I admit to a preference to brewing European style beers, as I can get multiple IPAs on tap at all the breweries and bars in town. I do brew an occasional IPA, because it is difficult to find one with the old school hops that I prefer - Chinook, Cascade, Centennial and Amarillo. Too many have those tropical fruit (which are okay) or dank (which I dislike) hops.
