You can find the Children's Library on the second floor of Lamberg castle. The librarian will let you know what you need to do, to become a member of the library. 
You can be a member of the children's library until the completion of elementary school.

Registration is free, but parental permission is required, therefore it is good to be accompanied by a parent at registration. If you come alone, you can take home the registration form. 

In the Children's Library you can find different non-fiction books, novels, poetry books and different journals.
