This article offers an introduction to the history and formation of the Archive of the Finnish Literature Society (FLS or SKS) – especially the collection of literature and cultural history – and the impact of some recent research projects utilizing materials stored at the Archive. One of these focuses on questions that are relevant to the Archive itself: Whose history has been recorded? What have been the criteria for the selection of the materials? Whose materials have been ignored or forgotten? Recently, there has been a growing demand to collect archival materials on minorities and make the existing archives more accessible and visible for researchers and activists.
