Thank you for your question.
It is clear that, in the publication world, information has to be purchased. Quality information is not free. We rely on quality information, and there is, of course, a cost related to that.
With the model where collections are purchased, especially digital collections, the main issue is the price of membership, which is paid every year. Their percentage increase is fairly standard. That aspect is also subject to copyright. It is impossible to get the same information, in the same way, from a provider who asks for less. If we really need a scientific journal to answer a specific question, we will not really find the information elsewhere for less.
Investment must be made for us to be able to purchase quality information Parliament needs to do its work. Publication models really represent a challenge, but that increase enables us to ensure sustainability for a few years.
