Comprehensive History and Culture of Andhra Pradesh

by Tulika Press has come out in three volumes so far ( I bought them last year and started browsing through now). These volumes cover the periods upto 500 BC, 500BC to 624 AD, and 624 to 1000AD and edited and written by different scholars. The second volume has several interesting articles by P.V. Parabrahma Sastry like "Language, Literature and Script in Early Historical Andhra". The period 1000 to 1649 is covered in a book by Cynthia Talbot "Precolonial India in Practice :Society, Region, and Identity in Medieval Andhra".
