One of the largest libraries in Paris, very well equipped and provided.
A paradise for students or curious people who want to know more or do research.
There is also an archive of all the press since Methuselah.
There are balconies / terraces for smoking, flirting and watching the rooftops of Paris when we take a break from reading.
Coming early, sometimes a little before the opening, you will avoid the tail.
