This is a renewed database and an interface with a search engine for searching and analyzing text reuse clusters in the Swedish-language press from 1645 to 1918. It covers material from Finland, Sweden, and also the United States. It has been produced by the project Informationsflöden över Östersjön: Svenskspråkig press som kulturförmedlare 1771–1918 (Information Flows across the Baltic Sea: Swedish-language press as a cultural mediator, 1771–1918). The database was first opened online in October 2021, and it was replaced by an updated and expanded set of database as well as search and analysis tools in August 2023.
