SAMLA has developed a thesaurus in collaboration with the Swedish Institute for Language and Folklore. It is based on the thesaurus from the Folklore Archive in Uppsala. The ambition is to use it as a trans-national Scandinavian thesaurus.

The Uppsala catalog was chosen as the starting point because it is very comprehensive. It also originally formed the basis for the catalog at the National Folklore Collection in Ireland. Thus, it has proven to be suitable across national borders. In the work of designing the digital thesaurus for SAMLA and ISOF, the thematic catalog from the Norwegian Folklore Archives has also been used as a comparison.

The thsaurus is located at KulturNav, Tesaurus for SAMLA og ISOF (Universitetet i Bergen)
