Martti Rapola (1891–1972), a distinguished researcher of Old Literary Finnish and Finnish Dialects, compiled extensive material on 19th-century Literary Finnish, which he organized according to its significance. From these pickings made in the 1930s and 1950s, Rapola's 19th-century vocabulary was created, comprising a total of 44,000 headwords. Rapola made use of this material in many articles published in the 1940s and 1950s and in a selection published in 1960, named 'Sanojemme ensiesiintymiä Agricolasta Yrjö-Koskiseen', which, as the name implies, contains a vocabulary established in Literary Finnish. The material published online is based on the original headwords, which have been selectively submitted as a database. It contains information about a total of 5600 words, divided into 1070 concepts. This is about a quarter of the original data.
