Infomine, not a list of links as such but rather a search engine which indexes documents mainly from a handpicked list, a list styled as “Scholarly Internet Resource Collections”.
Searches done on Infomine will likely reveal some of the “hidden internet”, parts of the online world that are often inaccessible to search engines such as Google and Yahoo, or are simply not ranked highly by the engines for complicated reasons.
One downside of Infomine is that some resources located by it are actually off-limits to general surfers, you need a log-in, or need to subscribe.
However on the whole a great deal of hard-to-find resources and pictures for research or general purposes can be located at Infomine.
