More bad news from the world of professional book reviewing: Publisher’s Weekly is reporting that Nielsen Business Media has announced that it will close the highly influential book review publication Kirkus Reviews as well as Editor & Publisher magazine. In publication since 1933, Kirkus Reviews publishes roughly 5,000 book reviews annually covering a wide variety of genres. Its closing will undoubtedly cause a significant decrease in the availability of professional, well-written book reviews. Editor & Publisher, the “bible of the newspaper industry” has been in print even longer; tracing its origins as far back as 1884.
