How can I extend the time of borrowing books?

You can renew your loans in Helmet web library, if your loans are from Helsinki, Espoo, Vantaa or Kauniainen libraries. You need your own PIN code which is attached to your library card number. You can get your pin code from your library.
1) go to www.helmet.fi (choose from the upper right corner language "in English")
2)The upper right corner: Your Record
3)Now write your library card number and pin code and then log in.
4)You can see your loans and choose what to renew. You can renew your loans three times, if there are no reservations. If you have payments of 5 euros or more for library then you can renew your loans only after you have paid so that your fee is under 5 euros.
