Most of them make sense to me. I don’t know some of them but then I don’t know everything. The methodology can be discussed (and indeed, a pre-selection of 200 books is at the same time a lot and not that much), but none of these lists can be perfect.
Out of curiosity, which one would you remove from the list, and which ones would you add?
For what it's worth and what mostly triggered my comment, I expected 1984 to be on the list but thought it missing, but as mentioned in the other comments I was wrong about that, it's just listed with the numbers written out. Le petit prince I wouldn't have wanted on the list, I know it's popular and french, but I never got the appeal. Ulysses, as mentioned below, surprised me as I thought it's only popular in some countries, and regardless of that I think its just not readable. I would kick out two of the Lord of the ring books, one is enough and it's not like each of them had a different impact.
Maybe even more subjective, The Hound of the Baskervilles is important and well known and everything, but does it really held up when you read it today? If not, which would be my opinion, should it be on the list regardless? And I'd consider replacing Thomas Mann Zauberberg with Tod in Venedig, just because I liked it a lot.
For missing books: Louis Begley is an author I felt to be missing, probably with Wartime lies, or About Schmidt. The first Harry Potter as well, but I understand that in 1999 it was too early for that judgement. Stephenson's Snow Crash is missing, maybe replaceable with Neuromancer to have something of that genre. Talking german literature with Thomas Mann above, Alfred Andersch Die Rote would have a place on my personal list, as well as Die Wand by Marlen Haushofer. Haruki Murakami is missing, though maybe with 1Q84 he better fits into a list of the current century. Stephen King? Paul Auster? Philip Roth? Though maybe that would be for The Human Stain, and that's from 2000.
As an aside, I was happily surprised to see The Master and Margarita on the list. It's one of the more known books that I thought had a very special charm, but not one I'd expect to see working on many, as one would have to have read Goethe's Faust and liked it...

For example, 1984 is missing, and Louis Begley Wartime Lies. And I wouldn't have expected Ulysses in there given the french source, for me it was incomprehensible gibberish and I thought only the US ranks it high. But that gibberishness makes it certainly memorable, so given the question it fits.
>I thought only the US ranks it high
Joyce never even set foot in the United States... You could say this about The Great Gatsby, which US sources might rank in the top 5 compared to 46 in this list.
> "what stuck in your mind"
That's strongly correlated IMHO; and I don't really see any objective metric for the influence of a book anyway.
> He used to hold long book club style readings of his books among the prominent literateur in his times to exactly impinge in their minds that what he writes is clever and not gibberish.
My was so clever, that he had to verbally harangue people into finding his writing clever.
When I don't know, I ask and don't judge (and lacking omniscience, I don't judge anyway).
I'm aware that some think this book is influential, I'm not clear on how widespread that belief is. Also, whether regular readers really like it. And no, Wikipedia does not clear that up.
