In the top right corner of the website you can login to My Library, your personal library. Here you can view, renew and reserve materials, and change your personal information.
Your account number (klantnummer) can be found on your library card. Usually, it contains 11 digits and starts with 70.
Your default 4-digit PINcode is generated out of your birth date. The first two numbers are the birth day, the last two numbers the birth year. Someone born on May 26th 1972 will have pincode: 2672.
It is possible to change your PINcode after login. If you forgot a changed PINcode you can have it reset at the cusomer service desk in the library. Please bring a valid identity card.
