The Archives of Latvian Folklore began compiling the catalogue of functional groups for charms in 1926. Kārlis Straubergs was also involved in the creation and arrangement of the catalogue. Each unit of charm text was typewritten on a small piece of paper, and the pieces of paper were then grouped according to the functional use of the charms: erysipelas charms, colic charms, toothache charms, etc. However, the catalogue was never finished; work on it ceased as the political environment in Latvia changed following the Second World War and was never resumed. Currently, the catalogue contains more than 19,000 charm units divided into 186 functional groups.
