In concrete terms, we apply the 15% limit. When professors give library employees a list of texts they want to reserve digitally, which is the case for the vast majority of reserved works, we can very easily see whether the excerpt accounts for 15% of the content. We count the number of pages of the work in question and not chapters. We also have a document we can refer to in our discussions with professors.
In order to be able to report to Copibec on a quarterly basis, we make note of all the decisions we make on texts put on reserve or those we have used to make printed textbooks, or all courses. It is clearly an advantage in terms of what we do on a daily basis with library materials.
