The museum has a very detailed history of the Holocaust, including France's role in deporting French Jews (though I think they could go further in taking responsiblity for their collaboration with the Nazis). The signs are all in French and English and there are audio guides in different languages (though they were very long and we ended up not using them for most of the exhibit). The walls of names are a powerful memorial. The research into the names is impressive, the reason for it heart-breaking.
Unless you have a great interest in the Holocaust, I highly recommend visiting the Memorial des Martyrs de la deportation which is behind Notre Dame.
