Kudos to Eugene Volokh for telling apart Ilya Somin and Ilya Shapiro:

Apologies for the two self-promotion posts in one day, but I thought I’d mention that Cato has put together a slightly edited and improved version of my posts on Hobby Lobby v. Sebelius in a handy little ebook, available from Cato (list price $3.99) or from Amazon. The book also includes a detailed foreword by Cato’s Ilya Shapiro (not to be confused with our own Ilya Somin).
