Here is all that I have come up with for Zecharia Sitchin.

More.

Is it possible to get more upload space? It's reading max. single upload size: 48mb, but every file I try to upload now comes back too big. If not, I'll wait a while and try again. I several more of Sitchin's books. Thanks.

Some more.

How much of his work can be verified?

There have been many researchers who have been working to verify Sitchin's work. As Sitchin claims to be one of only a handful of scientists able to translate the original Sumerian tablets into English, I think that for at least some of his work, we can look for other transliterations of the tablets. Here's a good site to start with, as they have translated, I believe to the best of their ability, all of the tablets. The Electronic Text Corpus of Sumerian Literature, http://etcsl.orinst.ox.ac.uk/edition2/etcslbycat.php

There have been some, as I'm sure you are aware, who disagree with Sitchin and his translations, but I think for the most part, his work seems to be about the best on the subject. There is a bit of a controversy going on about whether he is accurate about the presence of the Reptilian beings here on Earth, as David Icke has stated on more than more occasion that Sitchin would never approach that subject with an open mind, but that whole thing is up for debate anyway. But I do believe that just the privilege of reading Sitchin's material is something to behold. And as soon as I am able to, then I will upload the rest of his books onto this thread.
