Museum collections include approximately 10 000 objects and photographs. They also include documents, books and works of art. The collections depict deaf education, organizational activities, prominent persons in the community, sign language, and the work that the community has done to strengthen its own status and to achieve equality.
The collections cover a period from the late 18th century to the present day and are nowadays part of the collections of the Labour Museum Werstas.
