Dark Energy, dark matter and all that

For those interested in the incredible story of modern astrophysics, especially the dark matter/dark energy puzzles there is an excellent guide to resources. 

Pre-print of the Resource Letter BE-1: The Beginning and Evolution of the Universe,
by Bharat Ratra and Michael S. Vogeley, which has just appeared in arXiv has 
not only a very comprehensive list of sources, but readable introductions into what is what.

The only negative remark I can find, speaking from the point of view of an amateur follower of science, is that the publication is too conservative with respect to `official channels' of science dissemination. Yes, I know that there are copyrights and that scientific journals usually do not have free access. And it is `proper' to give references to peer-reviewed journal publications. 

But we do live in the Internet age, and astrophysics is, in fact, one of the fields where
e-pre-print is very much alive. As the Resource Letter publication shows itself. So, I find it a bit disappointing that there are no links to pre-prints in the publication. 
It would make the life so much easier...
