Unfortunately, however, there is another disadvantage I've become aware of over the past couple of years. There are for-profit websites that encourage students to take materials like mine and upload them into a database, where they then charge other students a fee for allowing them to access these files. (I'm not totally clear on how the sites work, but I think students are paid in some way—perhaps with site credit?—to upload these materials.) One such cite, 'CourseHero', has published over a hundred of my files on their site over the past few years. This is an illegal practice; these documents are my intellectual property, uploaded and sold for profit without my consent. Every few months I go through and check to see whether it's time to send a new DMCA takedown notice. (I am sending another today.) They do remove the files when I demand them to, but new ones always come up. To protect my copyright, I am required to spend a significant amount of my own time hunting down illegally uploaded material.
Besides the simple fact that is illegal, there are several reasons I am upset by this practice.
(1) It attempts to profit from the work I am doing for my employer and my students. My students at UBC are paying good money for the work I do, and the expertise I bring to bear, in the classroom. Some of that work is literally being stolen and sold.
(2) It removes the material from its appropriate context. I give my students these materials at particular times, and in a particular progression, for particular reasons. If one of my current students buys last year's notes and reads ahead, the material may not be presented in a helpful way at this stage in the semester. Indeed, in some cases, like when I make new conventional choices for logical notation in my formal logic course, last year's material will actually be misleading for this year's students.
(3) It interferes with my ability to assess. While I write new essay questions and problem sets each semester, it is helpful to be able to re-use some questions, or to introduce questions of a certain kind in assessed contexts. If students are able to download answer keys for previous semesters' material, I am less able fairly to assess their comprehension, since they had an unfair advantage. (Of course, this imbalance is particularly problematic when the advantage is offered to those able to pay for this service.)
(4) It violates the privacy of myself and of my students. The material will often discuss particulars of what ideas have been raised in class, including ideas generated by students. It is prepared for a particular audience, and not for public consumption. What students discuss in my class does not thereby become public knowledge. It also represents my own thinking about topics I'm often not publishing about—in some cases, I'm writing out my own relatively undeveloped philosophical thoughts, and in some, I'm playing devil's advocate or merely exploring an idea. In this non-research context, I won't always signal as clearly which is which than I would in something I'm intending for a public audience. It should be up to me whether to make this kind of content available to the broader public.

(5) It gives students with the resources to pay for illicit notes an unfair advantage over students who can't afford them.
So, three messages:
Students: It is important to understand that the materials provided to you by your instructors are not yours to do with as you please. At least at UBC, they remain the intellectual property of the instructor, and are protected by copyright law. I have been told that at some institutions, they are the property of the university. I'm not sure. But you should certainly not assume that you are within your legal rights to sell the material your instructor gives you to any third-party. It might even be possible to prosecute students who violate instructors' intellectual property rights in this way. If you're not sure whether you have an instructor's permission to share course material, you can always ask.
Instructors: if you feel as I do that you don't want such materials to be sold by corporate websites, unfortunately it looks like you have to look out for this material yourself. I found a lot of things by searching for my name at the 'CourseHero' website; I found some other things not attached to my name by looking for course numbers. To demand the removal of material, you can send an email based on the following template. (At CourseHero, the address is firstname.lastname@example.org.)
