Jerzy Szałygin, Katalog Zabytkow Osadnictwa Holenderskiego Na Mazowszu (Warsaw: DiG Wydawnictwo, 2004). Much, but not all, of this book's text is available in an English translation at: Catalogue of Monuments of Dutch Colonization in Mazovia Unfortunately, the translation rendered the term Olęder into English as "Dutch." This sometimes creates the impression in the English-language text that the author meant persons descended from settlers from the Netherlands or Friesland, when he actually meant persons (most often ethnic Germans) living in villages organized under the Olęder law. Despite this translation problem, Szałygin's work is an excellent source of information for numerous villages in the subject region.
