ARCHIVE.ORG PDFs (best for researchers)
ARCHIVE.ORG provides an online viewer of the volumes, and you can also freely download the PDF files (useful for quick keyword searches). The volumes stored at Archive.org are medium resolution PDFs (about 150mb each).
There are also links to higher-resolution PDFs on bigwalls.net (about a gigabyte for the two volumes). The original posts on bigwallgear.com might be outdated as the book versions have updated research and new material, but I will leave these posts up as they still provide useful pages for standard Google keyword searches, and always appreciate comments (bigwallgear.com is a Substack email subscriber free publication, and includes other rambles from John Middendorf about climbing and gear innovation history).
