Book excerpt: This inventory provides a survey of the extant Yiddish sources in Dutch archives and collections outside of Amsterdam. Until now, an overview and quantitative summary of the available Yiddish sources in The Netherlands was lacking. The compilation represents only a modest beginning, for the amount of material that has survived is enormous. An inventory relating to the Jewish community of Amsterdam requires a separate volume. The present inventory aims to stimulate new research-projects on the history of Ashkenazi Jewry in the Netherlands and to facilitate the research of the west-Yiddish speech variant that was spoken by the Ashkenazi Jews in The Netherlands.
