Obviously, the additional demands in the educational sector where you are trying to push the bounds of knowledge lead you to invest in significant machinery: the updating of buildings and of course materials, and hiring good people who are exceptionally good teachers and exceptionally good researchers to staff these facilities. All these are fought over right now in the international community. These are precious commodities and things that you are trying to be right on the leading edge of at all times, which, as in any sector, will make it more expensive.
It's also one of the reasons there are significant pushes for cost efficiencies throughout the post-secondary education sector. Governments and the public have demanded that. If these textbooks are good, are there other models? Something like an open educational resources model has demonstrated there are other really effective means by which to produce some content. So if a calculus 101 book, which has very consistent content, can be built on in a public environment, it can be very successful. It will be rated just as good as the textbooks purchased in other situations.
We think, again, that this is part and parcel of operating in a public environment and something in which, overall, we think all of the actors want make sure they are getting the most bang for their buckāand that includes the public. That is one we understand. We also understand that we will all still need to look to those kinds of efficiencies to make this both effective and affordable for everyone.
