lol, yeah that's our shibboleth/athens single sign on stuff. the library pays for all sorts of resources (publications, databases, etc) which are available to the students when they are logged in to the university network whether on or off campus. Mostly those urls are hidden in buttons and links, but not in the pdfs as buttons don't work.
If there were many people saving the pdfs that might get refined a bit, but it isn't worth the time since so few people actually use the pdf button. Our main docs (library workbooks) don't have a pdf button, only the assignment planner because that was a requested feature.
If it were up to me students would be able to log in and save/update their schedule and then it would be a really useful tool. But logins are a little way ahead on our cautious road map
