So I entired "Voltaire" in the catalogue's online search machine. Result: 208 volumes (no surprise), one of which isn't a book but a handwritten manuscript, though it says "Abschrift", i.e. not an original Voltaire manuscript, a copy someone made by hand. Of "L'enfant prodigue". Sadly, it's not immediately mentioned whether among those 208 Voltaire volumes there are copies with a handwritten dedication.
Meanwhile, Jean-Jaques Rousseau is present in Fritz' library, too, but "only" via 38 volumes. Then I got daring and tried Beaumarchais, but nope, the author of Figaro didn't make the cut, only a today unknown earlier namesake who wrote a book called "Histoire generale De L'Allemagne".
Oh, and there is a personal Hand written copy of the French translation of Christan Wolff's book that was made for Fritz by Suhm in 1736. (The one Voltaire thought back then Fritz himself had translated.)
