This just in from an NBCC member who received it from Publishers Weekly’s reviews editor:
We are under constraints to reduce our expenses and must reduce the fee we pay to reviewers. Any reviews assigned after June 15 will be billed at $25 per review. However, you will be credited as a contributor in issues where your reviews appear. Please know that we value the work you do for us. Your astute reading and writing are what make our magazine so valuable in the industry and we regret this necessary action. All of us here are also experiencing change but we expect that we will continue to be the gold standard in book reviewing.
