Look at a review of the same book in both The Nation and The National Review to see vast differences of opinion Are intended for the educated reader, but not necessarily the scholar Offer opinions or viewpoints on cultural or political affairs, usually with particular bias Are written by professional commentators, columnists, and other opinion leaders
