I don't know if Saxon is still alive, but the Poor man's James Bond is doing fine 
Salinger wasn't "isolated" he was just more of a loner, he was at Dartmouth for 2 basketball games just last week.
I used to have the set of PMJB and his Survivor series plus the smaller publications but they have gotten away from me over the years. I found a site that seems to over the whole thing on CD... not sure if having Survival reference works on CD makes sense.
Yeah, about Salinger. To the News Media, if you had fame and now don't choose to show up at every media event possible and spout your opinion on everything from Global Warming to the fate of blind cave fish, you are a recluse.
Of course, he wrote Catcher when he was about 30 and his own "coming of age drama" was still a fresh memory. It may be that he demanded his picture be taken off further publications of the book because, at an advance age, he didn't feel quite the tolerance for all that Teenage Angst anymore.
