Based on recent excavations at Harappa, it is possible to determine that square seals with animal motifs (such as the elephant) and possibly the short horned bull are among the earliest form of seal with writing.

An article by Dorothy MacKay, wife of Ernest J.H. Mackay, describing excavations in 1935-36 at the ancient Indus manufacturing site of Chanhu-daro, 80 miles south of Mohenjo-daro. This illustrated July 1937 article from the popular US magazine Asia is a nice summary of the finds at this sophisticated ancient Indus site where, among other things, long carnelian beads, toys, seals and weights were made.

A brief article by Paolo Biagi and Renato Nisbet which discusses the Palaeolithis sites at Ongar (Sindh, Pakistan), their potential value, the dangers of losing the site and unwillingness of local government to secure it. The article includes nearly a dozen color images including maps, diagrams, and on-location photos of the site.

A very interesting and informative article that starts bringing the adjacent ancient state of Dilmun on the Arabian Gulf (many of the finds have been in present day Bahrain) to light, and what must have been a very rich trade and cultural relationship with ancient Indus cities.
