Archaeological literature on the Stone Age?

I have asked questions similar to this before. I am writing a "paleofiction" and looking for information on stone age technology outside just the basic information. Does anyone have some in depth info online that maybe I have overlooked? Like I said, I have asked this question before and I have only been told to look where I already have looked or told to read Jean M. Auel (which I have). Particularly at the moment I would like photographs of stone tools outside of the Aurignacian or Gravettian, for example, the Antelian culture and cultures of the Near East. Where might obscure information like this be archived online?
