The book is an annotated list of the main documentary sources on the socio-economic and political development of the Kazan Territory in the second half of the 16th and 17th centuries. For the first time, a single collection of both published and most archival (unpublished) materials is being attempted. Each document is accompanied by a short title and a legend, which indicate the content and nature of the issues raised in the source, the location of the document and its main publications in full form or in extracts.
