The other two are Blacklisted by History: The Untold Story of Senator Joe McCarthy by M. Stanton Evans and The Liberal Mind: The Psychological Causes of Political Madness by Lyle H. Rossiter Jr., MD.
Try going to your bookstore and asking for these books. I asked for Liberal Fascism at my bookstore and I was told that they didn't have it in and "we won't be ordering it." (IOW, we're good libs, so you're not allowed to rad that -- thus proving Jonah Goldberg's point.)
After reading these three, I plan to go back and re-read Michael Savage's Liberalism Is a Mental Disorder and Ann Coulter's Treason. (Hey, ask your bookstore for those, too.) :)
Here is another one that sounds interesting:
