Roshnarose, you have really sucked me into a black hole here.
The 1001 books: I've read 107, plus 16 that I started and couldn't stomach.
The paintings: that's really hard. Here is a painting that you've seen in a lot of reproductions, and it's in the Uffizi Gallery, and you were there in 1967. Do you remember if you saw it, or only remember the reproductions? And what about the 4 or so Rothkos, "Untitled" in private collections. How do you know if you saw them in that Rothko show you saw? There were only 18 that I could swear in a court of law that I'd seen, but a lot of those brought back good memories. No El Grecos in the list. That's wrong. I'll remember to my dying day the El Greco exhibit at the National Gallery of Art in the '90s, where they had assembled what must have been a large fraction of his paintings. I saw it three times, and bought the catalogue, which is a pale ghost of the vibrant, glowing originals, still bright in my mind.
The classical music: that doesn't belong here, since we're books, not music, but I found their choices less defensible here--not the works, but the recordings. I count 23 recordings that I've heard, and mostly own. I count 71 that I own recordings that I can argue are as good or better than theirs. Some of their choices, especially the Bach, I feel are not as good as other available recordings.
It's a good thing the wine list isn't up and running. That could be lethal to check out.
