I really want a search engine that just pulls from pdfs and other documents. Nearly every time one pops up in my results it's exactly what I wanted. I have like 30 random pdfs saved that I got primarily through these means at this point. Supposedly the early web was mainly just documents with hyperlinks. I wish it was like that now. Now wikipedia has killed most specialized information repositories, at least in terms of findability, and what does exist is primarily in terrible javascript sites that take minutes to load and generally require an email based account to access.
