Let’s see . . . 18 in the room I’m in now, my study. I’ll walk around and count the rest.
Ok, about 10 in the living room and the same in my husband’s study.
About 145 in the little room we call the library, 16 in my sons’ rooms, and 12 in the bedroom.
I’d estimate about another 6 that are currently in random stacks here and there.
That’s 217.
I have no idea how many more are in boxes in the basement and the garage.
The actual measured total probably wouldn’t exceed yours, @BarnacleBill, but it’s still substantial. Your library must be truly impressive.
So—I think if I were ordering bookshelves, I’d probably try to keep it down to about 200 linear feet. But I’d still end up with what I have now: 3-foot vertical stacks in the corners of rooms, double-depth rows of paperbacks, scores of books shoved in sideways on top of rows, and, inevitably, random stacks here and there.
