What an interesting question! I’m not sure this is a complete answer, since there doesn’t seem to be a quick and easy way to compare my library to the Legacy Libraries. But from my quick glances through the profile pages, I share a lot of books with interesting dead people!
I share books with , in no particular order: e.e. cummings (2), John F. Kennedy (1- Lolita, of all things), Sylvia Plath (2), Marilyn Monroe (1), F. Scott Fitzgerald (3), Samuel Roth (2) and Walker Percy (3). It’s very interesting that I share 4 books with Ernest Hemmingway, an author I don’t particularly care for. We share The Gentleman’s Companion (my favorite of my antique books), The Great Gatsby, Lolita, and The Three Musketeers.
The biggest surprise – I share 7 books with Carl Sandberg, who was apparently a Nero Wolfe fan! We have 5 Rex Stout titles in common (The Case of the Black Orchids, Champagne for One, The Golden Spiders, In the Best Families and Prisoner’s Base), as well as Lolita and Orlando by Virginia Woolf.
Also interesting is that I share the same books/authors with several people – various titles by Virginia Woolf, obviously Lolita by Vladimir Nabokov, and The Great Gatsby by F. Scott Fitzgerald. A great question and a great way to learn more about my own library!
