Statistics from the National Booksellers Association indicate that during the last five years most bookstores have started to experience declining revenues from the sale of fiction, despite national campaigns to encourage people to read more fiction.
Evidence
Statistics from the National Booksellers Association indicate that during the last five years most bookstores have started to experience declining revenues from the sale of fiction.
Conclusion
National reading campaigns to encourage people to read more fiction have been largely unsuccessful.
Evaluate
It could be that declining revenues from the sale of fiction at bookstores indicates that people are reading less fiction, but other explanations are just as likely. Perhaps people have relied more on the library during the past five years or it could be that revenue per book has fallen and that while people are ready just as much fiction as before, they’re spending less while doing so.
