The Types of the Scandinavian Medieval Ballad: A Descriptive Catalogue (TSB) is the designation for a cataloguing system for Scandinavian ballads.
It is also the title of the underlying reference book: The Types of the Scandinavian Medieval Ballad: A Descriptive Catalogue, edited by Bengt R. Jonsson, Svale Solheim and Eva Danielson, in collaboration with Mortan Nolsøe and W. Edson Richmond, published in 1978 in two places: as volume 5 of the series Skrifter utgivna av svenskt visarkiv (Stockholm: Svenskt visarkiv), and as volume 59 of series B of Oslo's Instituttet for sammenlignende kulturforskning (The Institute for Comparative Research in Human Culture) (Oslo, Bergen, and Tromsø: Universitetsforlaget; ISBN 82-00-09479-0).
It attempts to classify all specimens of traditional ballads known in one or more of the Scandinavian languages (Danish, Norwegian, Swedish, Icelandic, Faeroese, and the extinct Norn).
