As a high school English teacher for 35 years, my main concern is always what kind of setup will make it easiest for kids to get books.
The B&N bookstores are wonderful, but expensive for the average family. Avid readers develop by reading book after book after book. My avid-reading students (and these are the kids who go on to the top colleges) report reading three or four books a week, especially in elementary school. They like series books, and will read through a thirty book series in a matter of months.
They used to have more luck getting these series books in a library, but libraries have been underfunded for so long that that’s not usually possible anymore.
For me, the knight in white armor has been Amazon. Once a kid has an e-reader, there are literally thousands of free and very low cost books on Amazon. There are all kinds of series that are self-published, and sell for a dollar or two a book. When most kids have gotten access to an e-reader and an Amazon account, they will be self-sufficient about getting books, no longer having to talk someone into driving them to a bookstore, and then paying six or seven dollars for a slim little paperback. It might be the end of the stagnant reading scores.
What I’d like to see B&N do is open up a used book section for children’s series books. This would get kids back into bookstores, and make the development of avid readers much more affordable for the average family.
