I have most of these, but don't want to part with them, so I'm just writing to encourage you to keep looking for these books. I've had some success on eBay, and some on Bookfinder (www.bookfinder.com
), which brings together lots of vendors of used, rare, & out-of-print books. And, although it's an unpredictable process, I've had a lot of success at library book sales, etc. Generally, few people want books on these topics, and so they can be acquired almost nothing (e.g. -- I found an autographed copy of Grete Waitz's World Class). So, good luck in the search!
Here's another one you might look for:
Title: Jim Ryun: Master of the Mile
Author: John Lake
NY: Random House 1968
It's interesting mostly because it was published before 68OG, so it's looking at Ryun before the race that would be (for a lot of people -- not me) the definitive moment of Ryun's career. It's reasonably well-written, w/ lots of good pictures.
