At the library in Venice, if you use the 'What is' command and hover the pointer over the librarian, it says he is Irene. Irene is a different character earlier in the game (Jones' secretary at the college), so that name is incorrect.
This glitch happens in both the EGA version and VGA remake of Indiana Jones 3 in ScummVM.
When I tried it in DOSBox, the What is command didn't say anything about the librarian.
I've included saves for both versions in ScummVM, and a save of the EGA version I took in DOSBox with the original .exe
