I've been trying like hell to get a copy (on VHS or DVD) of Buckley's one-hour interview of Borges done for Firing Line in the 1970s. I know that it was available on VHS for a short time, but I can't seem to find it anywhere.
If you ever do find a copy of that interview, please let me know. I've got a CD of Borges being interviewed in Spanish that I got on e-bay. It's worth having. The 4-CD "This Craft of Verse" is good as well, a little repetitious, but hey, it's Borges.
I'd love to find that as well.
