Unpublished works getting documented has become a rare phenomenon in the Tamil context, and this book is one such treasure. Water resources, agriculture and related issues, the interest of rulers in agriculture, oppressed communities, caste relations and the many faces of Nanjil land between AD 13 17 are found in this book. The documentation is meticulously executed, with reference to records and culverts and hence is as useful to a researcher as it is enthralling to an interested reader.
