The unavailability of the information was placed firmly at the feet of language and publication patterns for Scandinavian scholars. That lack of access and information time lag is also true in the United States. Most information on Scandinavia lags five to ten years before it is commonly available in the United States. The best and most current information is often in articles, conference papers, or theses and dissertations. That information is often not in English but rather in Norwegian, Danish, Swedish, Finnish, Russian, or Icelandic.
Language is one reason for the delay and publication patterns is another.
One publication pattern typical of Europe is the publication of new research in the local historical group journal not in a major journal as in the United States. Another difference between the United States and Europe is publication of a thesis or dissertation by the author. It has not been common in the last few decades for an academic in the United States to pay to publish a thesis or dissertation. This is a pattern that is changing and American scholars are more and more likely to publish an initial scholarly work in the European pattern. The end result is that new information is difficult to find in English unless one has access to a major university where Scandinavian studies, languages, and specialists congregate or unless one regularly visits Scandinavia.
