I'm opening this topic for things that don't really rate a whole thread of their own.
In particular: Like everyone else, I have haunted used book stores for some of my stuff. Several of my books have written inside them: "Grover's" or at least that's what it looks like.
Grover knew his stuff pretty well. He/she wrote a lot of margin notes, explanations, opinions, corrections, etc. in all the books.
Anyone know who Grover is or was? If he's still around he should join us here.
