You must overcome any shyness and have a conversation with the librarian, because he can offer you reliable advice that will save you much time. You must consider that the librarian (if not overworked or neurotic) is happy when he can demonstrate two things: the quality of his memory and erudition and the richness of his library, especially if it is small. The more isolated and disregarded the library, the more the librarian is consumed with sorrow for its underestimation. A person who asks for help makes the librarian happy.
Umberto EcoMusical compositions can be very sad - Chopin - but you have the pleasure of this sadness. The cheap consolation is: you will be happy. The higher consolation is the pleasure and recognition of your unhappiness, the pleasure of having recognised that fate, destiny and life are such as they are and so you reach a higher form of consciousness.
Umberto Eco
