Ragnar Frisch meticulously preserved his scientific correspondence throughout the entire period he was connected with the University, i.e. from around the mid-1920s. He kept letters received and copies or drafts of his own letters. His correspondence was transferred by Trygve Haavelmo as executor of Frisch’s will to the University Library, which later transferred the correspondence to the Manuscripts collection (Håndskriftsamlingen) of the National Library of Norway. More letters were found in Frisch’s archive later and merged into the correspondence collection, which now contains 10 896 registered letters, whereof 5308 letters are to Ragnar Frisch, 4675 letters from Ragnar Frisch (and, as attachments, 913 letters to and from persons other than Ragnar Frisch).

The letters of the Frisch correspondence collection in the National National Library of Norway have not been digitalized and are thus not available on web site. The aim of the archive project is to have selected parts of the collection made available by transcription or scanning. So far the complete collection between Frisch and Eugen Slutsky have been transcribed, see below.
