It has come to my attention lately that many of the magazines, on-line commentaries, etc. charge for reviewing books, either directly or indirectly by linking the review with the purchase of advertising in the publication. In each case, when challenged, each publication insists it has done nothing wrong. Most of them also will take 'free reviews", but these are, understandably, placed at the end of the list and never surface to be reviewed. What are your thoughts on this practice?
Have you ever paid for a review?
If you know a publication charges the author or publisher for writing its reviews, does it change the way you evaluate the review?
What IS ethical?
