My article “Ayn Alissa Rand (1905-1982)” was first published in the IEP in 2001. The original article focused on Rand’s life and times and some issues in her ethics. This update expands that treatment slightly, mentions a broader range of criticisms, and adds to the bibliography some of the scholarship since then.
The encyclopedia is edited by James Fieser (University of Tennessee at Martin) and Bradley Dowden (California State University, Sacramento) and contains a wide range of professional entries on major philosophers and philosophical issues.
Suggestions are welcome in the comments below for future updates.
