@Philreedshikes I've got a first edition of MFOTH on my shelf, right next to the 4th, 5th, 7th, and 8th. It is interesting to compare comparable section of the various editions. Rappelling, for example, expanded enormously over the years (and rightly so).
Do you have Handbook of American Mountaineering, 1942, by Kenneth Henderson? That was recommended to me back in 1957 when I became interested in technical climbing and mountaineering. Discharged from the army in 1961, i got my grubby mitts of MFOTH, thank heaven, and that was my bible in my early days in the NPS. Fabulous work!
I've got lots of old stuff handing around...What else do you need??
