I'm such an old fart that I started buying books on film and TV and radio and music when, for television, the entire shelf of books was only a couple of them. You go into the '70s before you start getting books on TV that you start wanting to collect. And by the time that you get to something like the Brooks and Marsh book it's invaluable. My house got hit by lightning in 1989 and burned down. And I got more than a half dozen Brooks and Marsh books sent to me by friends immediately, as though that's what you need more than clothes or food. That's how treasured that book was.
