It's definitely in there. She may assume the reader knows this history:
"For most of human history, most people could not read at all. Literacy was not only a demarcator between the powerful and the powerless; it was power itself. Pleasure was not an issue. The ability to maintain and understand commercial records, the ability to communicate across distance and in code, the ability to keep the word of God to yourself and transmit it only at your own will and in your own timethese are formidable means of control over others and aggrandizement of self. Every literate society began with literacy as a constitutive prerogative of the (male) ruling class.
"Writing-and-reading very gradually filtered downward, becoming less sacred as it became less secret, less directly potent as it became more popular. The Romans ended up letting slaves, women, and such rabble read and write, but they got their comeuppance from the religion-based society that succeeded them. In the Dark Ages, a Christian priest could read at least a little, but most laymen didnt, and many women couldntnot only didnt but couldnt: reading was considered an inappropriate activity for women, as in some Muslim societies today.
"In Europe, one can perceive through the Middle Ages a slow broadening of the light of the written word, which brightens into the Renaissance and shines out with Gutenberg. Then, before you know it, slaves are reading, and revolutions are made with pieces of paper called Declarations of this and that, and schoolmarms replace gunslingers all across the Wild West, and people are mobbing the steamer delivering the latest installment of a new novel to New York, crying, Is Little Nell dead? Is she dead?"
Re: Potter, she was making a point on the expectations of today's publishers and stating her preference if she were one. HP and Tolkien will both be read, eh?
"A few steady earners, even though the annual earnings are in what is now dismissively called the midlist, can keep publishers in business for years, and even allow them to take a risk or two on new authors. If I were a publisher, Id rather own J.R.R. Tolkien than J. K. Rowling."
She's also talking about the perceived value of books. I noticed the HP books show up in droves in thrift stores. People hung on to their Tolkien a bit longer -- many probably still have their childhood copies.
"To me, then, one of the most despicable things about corporate publishers and chain booksellers is their assumption that books are inherently worthless. If a title that was supposed to sell a lot doesnt perform within a few weeks, it gets its covers torn offit is trashed. The corporate mentality recognizes no success that is not immediate. This weeks blockbuster must eclipse last weeks, as if there werent room for more than one book at a time. Hence the crass stupidity of most publishers (and, again, chain booksellers) in handling backlists.
"Over the years, books kept in print may earn hundreds of thousands of dollars for their publisher and author. A few steady earners, even though the annual earnings are in what is now dismissively called the midlist, can keep publishers in business for years, and even allow them to take a risk or two on new authors. If I were a publisher, Id rather own J.R.R. Tolkien than J. K. Rowling."
