I've been thinking about this story reported in GalleyCat earlier this week. It's about a book called Just Like Us: The True Story of Four Mexican Girls Coming of Age in America by Helen Thorpe. The book was released to "sluggish" sales last September, but two months later it enjoyed "an unexpected sales bump--defying publishing expectations with her late-blooming book."
What's interesting to me is that the author attributes the book's late success to reviews in traditional print outlets. It started with "a lovely review" in the November issue of O Magazine. Following that, the book was named one of the best books of the year by both the Washington Post and New West. Then came reviews in The New Yorker and the Atlantic.
The lesson for me is that publishers shouldn't dismiss the power of those old fashioned, old media, stone age print reviews just yet. The traditional media outlets may still have some juice left in them.
