For the Imatra collection, the library acquires material made in Imatra, made by the people of Imatra and dealing with the Imatra region. The collection has more than 1000 titles of books, magazines, sheet music and recordings. More detailed information on titles can be found, like other material, in the Heili online library. The material of the Imatra collection can be consulted in the main library. It is not borrowed at home.
The collection is kept in the Imatra room of the main library. The room is intended for reading and quiet work. Customers have access to a computer and a microfilm reading device for reading Ylä-Vuoksi's old vintages. Time is reserved for reading the microfilms from the staff; otherwise the room is free to use.
