During the last half of the nineteenth century through the beginning of the twentieth, around 1.3 million Swedes emigrated to America, which was over a fifth of Sweden's population at the time.
The National Library of Sweden has over one million pages from around 300 Swedish-language newspapers published in America. Their collection contains all the large papers and many small papers, which may have only printed a few issues before shutting down. There is a big variety, including newspapers from the big cities and from the countryside and liberal, religious and socialist papers. Jonas Ahlberg said that they wanted to reflect this diversity when they selected which pages to digitize.
