A special collection in the Folklife Archives is the watercolors, drawings, descriptions and notes that were created and compiled by Nils Månsson Mandelgren (1813-1899). His purpose was to collect material through extensive travels in Sweden, which showed the uniqueness of the indigenous culture. The collection, which includes about 100,000 records, is a documentation of the country's cultural history from ancient times to Mandelgren's contemporaries. It is a valuable resource for archaeologists and art historians as well as for ethnologists. The material was donated by Mandelgren to Lund University in 1889.
