Registration is only possible if you are a member of one of the participating libraries. You will find them in the selection list under "Register".  To register, select your library on the registration form. Then enter your library card number and your password for your library account.  If a login fails, the card number or password may be incorrect or the card may no longer be valid. To verify your library account, please contact your library via the "Contact" tab in the main menu. Select it there as "Desired contact person".
