The books are written in a question-and-answer format. Obviously, with titles like Invasive Species, Pandemics, and Overfishing, not every book in the series is of interest to libertarians. But aside from Libertarianism: What Everyone Needs to Know (reviewed by David Gordon here), these two books on the drug war are the two titles that libertarians would be the most interested in.

The three common authors of these books are all academics at major universities. Beau Kilmer is co-director of the RAND Drug Policy Research Center. The marijuana book also includes an additional author, Christina Farber, for one chapter.
