Here's the big 2005 paper Jensen co-authored with J.P. Rushton: "Thirty Years of Research on Race Differences in Cognitive Ability."
Any other suggestions for online materials?
Update: Mike Steinberg suggests:
Jensen comes in 47th place in "The 100 Most Eminent Psychologists of the 20th Century" Review of General Psychology, 2002, 6, 139-152.
