"33 Questions About American History You're Not Supposed to Ask," Tom Woods

Guest editor's choice. Finished reading this book a few days ago, and it's filled with great referencing material. If you're considering the purchase and can find the book online, I recommend any excerpts from "How Does Social Security Really Work?" and "Is Discrimination to Blame for Racial Differences in Income and Job Placement?" (chapters 13 and 18, respectively).
