The collection reflects the history of House Gideon Malherbe during its occupation by the Malherbes. The collection also includes documentation of the history reflecting the establishment of the Afrikaans Language Museum and the Afrikaans Language Monument. The museum further houses a modern multi-media exhibition that aims to give visitors an insight into the development of Afrikaans.
It also houses an extensive collection of early Afrikaans publications including Di Afrikaanse Patriot (an early Afrikaans newspaper) and Ons Klyntji (an early Afrikaans magazine).
Some of the large groups included in the holdings are the Nienaber, Bosman and Immelman collections, which cover early Afrikaans writers, publications and manuscripts.
Another interesting group is the photographic collection, which covers early role players in the recognition of Afrikaans, the ATA and their families.
