The Nordic meetings on Stratigraphy - 20 years and 10 meetings later.

The first Nordic Meeting on Stratigraphy took place in Stockholm in 1996. The tenth session in Helsinki 2015 opened for reflections from the earlier meetings. What was the original intention when we started the conference? Which topics has been discussed over time, what can we say about geographical and chronological issues? Is it possible to detect new ways of thinking concerning stratigraphy and contextual archaeology? These are questions that will be addressed in this paper. [ABSTRACT FROM AUTHOR]
