A Companion to Ayn Rand, edited by Gregory Salmieri and the late Allan Gotthelf and recently released as part of the prestigious Blackwell Companions to Philosophy series, is the “first volume to offer a comprehensive scholarly treatment of Rand’s entire corpus (including her novels, her philosophical essays, and her analysis of the events of her times).” In order to highlight the unique value of the Companion, ARI fellow Don Watkins interviewed several of the volume’s authors about their contributions.
