More than 200 peoples and ethnic groups are indexed on the basis of different sources. Underlying data are results of field research published as ethnographic monographies, essays or manuscripts which are used as "primary data" and subject-indexed by applying a highly complex and differentiated system down to the level of single paragraphs. The indexing is done according to the "Outline of Cultural Materials" (OCM) that contains over 700 different classification elements. Additionally, a keyword search at full text level is possible. The database is updated on a regular basis.
