Hi,
This might be off-topic, but there are some strange tales about Sitchin on this link that I have not found on any other website. Doesn`t really portray him as a reclusive.

Be it as it may, Sitchin has really no one to support him in the academia, all his claims he still has to prove as facts and that means a lot of labour.
