3 things here : 
1. "Choose" was conjugated without an "s" at the end, meaning it wasn't using the 3rd singular pronoun from the present verb tense, it used the 1st form of the imperative verb tense. In French, it's gonna be "Choisis" instead of "Choisit".
2. "Accéder", not "accède". Here, it's the opposite of the issue on line #335. I could give an explanation on that, but honestly, I don't think it's necessary, plus it's so complicated that I have trouble explaining it. I could try giving one though if it's requested. 
3. Correct me if I'm wrong, but I felt that changing that "Bibliothèques" part with french quotation marks and removing the "de" sounds grammatically better.
