There is now a memorial site for Hans Jürgen Eysenck, the famous and controversial psychologist.
The website includes free PDFs of many of his older works, including books going back to the 1950s! Some of these are actually quite informative, and I have previously reviewed some (Psychology of Politics, Genius: The natural history of creativity).

More to come! Suggestions welcome, especially if you are willing to do the work of collecting the works and adding content to a WordPress site. I can provide the hosting free of charge.
