There are two volumes which I had purchased at Ramakrishna Mission in Chennai.
These two books have articles dealing with Ancient Indian Society/Politics/Literature/ and lot of articles about lineage of different kings.
These two books gave me a gist of the Ancient Indian life.After every scholarly article,there is a reading list.Both the books costed me 160 Rupees(They are published by Ramakrishna Mission).But the information from all the Indologists is priceless.
The books are
Bharatatattva :Course in Indology Volume 1
Bharatatattva :Course in Indology Volume 2
One more site that I found -Archaeological Survey of India
