Comment Academic Repository (Score 2, Informative) 18
The NEC Research Institute hosts a very nice warehouse of academic literature. Claims to be "Earth's largest free full-text index of scientific literature."
Not all of the documents cited are available for download, but those that are are available as PostScript, PDF, and GIF.
Scripts generate papers that aren't cached in a specific format on request.
The page layout is familiar enough for those used to staring at lists of academic references, and is easy to follow.
