The Institute has comprehensive collections compiled over the course of more than 100 years.

Written language corpora

The Institute has several written language corpora containing texts written in Finnish, ranging from the birth of written Finnish in the 16th century to the 21st century. Most of the collections contain texts published before 1900.

The Corpus of Old Literary Finnish contains texts created during the period of Swedish rule (from the 16th century to ca. 1810). The texts in the Corpus of Early Modern Finnish date from 1809–1899. The corpus of writings from famous Finnish authors ranges from the late 19th century to the early 20th century. Modern Finnish is presented through a corpus of New Year’s Speeches of the President of the Republic, from 1935 to 2006.
