Kolberg did not conduct his own research on the terrain of western Slavdom. There is no evidence also that he had any direct contact to Lusatia or their inhabitants.
However, his archive contains some material related to this region. It includes translations and quotations from the collection by Smolerj entitled ‘Pjesnički hornych a delnych Łužiskich Serbow’, his own notes on language and literature, and a set of tens manuscripts from 1826-27 by Andrzej Kucharski a slavist who visited Lusatia. They include more than 260 texts of songs, most of them with melodies, and some notes on language, including unique instances of a dialect of the Drjowka neighbourhood.
