The National Archives publishes a renewed Diplomatarium Fennicum database on sources of documents concerning medieval Finland

The Diplomatarium Fennicum database will renew the infrastructure of Finlands’ history and research on medieval Finland, and it significantly improves the prerequisites for the national research in Finland. The database consists of the most important documents on the earliest preserved administrative history of Finland. It is accessible to everyone as an open online service.

The database strives to collect together, for the first time, all information on documents concerning medieval Finland. Versatile search properties have been created for handling the information and applications have been created for the visualization of information. The service makes it possible to research and work with the source materials via the internet. In the future, new yet unknown documents on medieval Finland will be published through the database and thus, the picture of Finland's early historical period will be made clearer.

The aim of the project, which started in 2015, is to create a modern research infrastructure for the research on medieval Finland’s documents. In the framework of the project, a new online service has been developed which includes documents on medieval Finland. This new online service will replace the previous text database which was much more cursory.

The Diplomatarium Fennicum database consists of over 6700 documents and over 23000 related references. The database combines the scientific editions of documents to original sources and to their digital copies. Furthermore, the database will be linked to the most important literature and foreign databases.

The beta version of the database will be published on 1 October 2016 at the Turku Book Fair. At the same time, Finland’s oldest preserved document, 700 years old king Birger’s Letter of Protection to Womankind in Karelia, will be celebrated.

The Diplomatarium Fennica project is being funded by the Kone Foundation.

The database can found on the webpages of the National Archives, on 1 October 2016.
