That process will continue.
From a general perspective, I can understand Mr. Brown's situation. This is the kind of thing that we struggle with as a teacher organization. I don't want to leave the impression that teachers are stealing from creators, because they are not doing that.
The fact that there has been a decline in textbook sales in this country is not because teachers are photocopying textbooks. It's because school boards and ministries have a finite set of resources for education, and they're trying to make it go as far as possible.
Instead of everybody getting a textbook, class books are bought, class sets, and everybody shares them. They pass them on to somebody else. That has reduced the number of textbooks purchased. The quality of textbooks is higher. They last longer because they're a standard set. There is a greater reliance on electronic information and digital information. There's a whole host of reasons why the textbook sales are slower, probably, over the last 20 years.
That said, maybe the number of texts is down, but the amount of money spent is still the same. It's increasing, as a matter of fact.
There's only so much of that pie. There are billions of dollars spent on instructional materials, books included, every year at the university level and at the K-to-12 level.
