I don't have that one but have 4 guidebooks to the Wind Rivers.... I got the one by Finis Mitchell (from the 1970s but a fun read) just before the printed copies ran out and the price escalated to similar levels.
Good luck! You might do just as well with maps and whatever trip reports you can find via google or YouTube. Even for an outstanding literary opus I wouldn't pay those prices! In my youth, lengthy trips were planned using just a Forest Service map, with occasional assists from the USGS maps (mostly dating from the early 1900s before the trails were built) and they worked out just fine. I'm wondering if we haven't all gotten spoiled!
