make a reservation for books that are already on loan. When the books are returned you will receive a notice on your institutional email account and you have 3 days to come and collect the book(s).
request a book that is not on loan but that you cannot come and collect before a certain amount of time. By means of the "Richiesta di prestito" link it is possible to book an item from home and to come and collect it within 2 working days (including the day of request).
check your library situation and renew the loan of book(s) you have.
