Student Card: Your TU Dublin ID card is your student / library card. Be sure to carry your card with you at all times as you will need it to access the library itself. You also need your library / student card to borrow books, laptops, etc.
Library PIN: You create your own library PIN in order to access your library account online. This allows you to see a list of books you have on your account, renew them once if they have not been renewed before, put holds on items that are presently on loan to someone else, read e-books off campus etc.
Borrowing: The library collections are divided into subject areas. Items in the collections have different lending periods'. Depending on what type of student you are you will have different borrowing rights.
Renewing and/or Returning items: You may renew a 'main lending' book once only. There are restrictions such as someone reserving the book which might stop you from renewing, however. If you need to return an item, you can do so at a self-service machine, or hand it in at the library service desk.
Reserving a book: If a book you wish to consult is on loan, you can reserve it so that it is held for you on its return. Just click the "Request" icon on the catalogue and enter your PIN to do so. You will get an email when it arrives for you.
