I am definitely a fan of M::FOTH from way back. I purchased the first edition in 1962 (just released from military service) and I had just enough outdoor experience to realize that this book was the real deal with good guidance from people who know their stuff.
The 1960 edition has 97 pages devoted to technical climbing (not counting snow and ice) while the 2010 version has 183 pages devoted to the same topic with far more detail. There is an entire chapter devoted to rappelling.
The introductory chapters on fundamentals is good stuff even for those who do not ever intend to tie in - good solid advice for the everyday hiker and camper.
