You cannot come to the library but you have ongoing loans which are soon due? No need to come! You can renew your loans online, using your reader account. Depending on the kind of item, you will be allowed to renew them for 7 to 21 days just like when you first borrowed them
Renewing your loans is only possible starting 5 days before the due date.
You are entitled to 1 renewal per item as long as it has not been reserved by someone else.
