I just discovered this resource via the Ancient World Online blog. The site has a number of scholarly monographs on Egyptology, Mesopotamia, Israel, etc. that can be downloaded as PDF. For example, click here for the books in the Mesopotamian category. One of the titles is Brown’s Mesopotamian Planetary Astronomy-Astrology.
Of course, if you want to believe the nonsense of Zecharia Sitchin, Jason Martell, Michael Tellinger, etc., avoid that title. (Danger: contains factual information actually found in the tablets).
Thank you this is a very nice resource! Excellent find!
