The material that tends to get copied and used in class for instruction is different from the material that is used for research. That's where you get the science, technical, and medical journal publishers. The five big multinational publishers are in that category. The licences that they have through CRKN are for the STM, science, technical, and medical journals. What gets copied and no longer paid for is the educational content, the trade content, the stuff that is used for instructional purposes.
Like what Frédérique mentioned about the experience in Quebec, and in the rest of Canada as well, what we saw historically was that, of the copies that they used to make and report to us, only about 15% was from STM, science, technical, and medical journals. The rest was books, and that doesn't tend to be licensed through university libraries.
