There are plenty of books, textbooks, and journals that just aren't online, and aren't in print anymore. The ones that are online just get squatted by publishers who want to collect rent long after the authors have died. It is frankly absurd to pay $20-$200 for a digital "copy" (so locked down with DRM that you often can't even open it offline) of an out of print book or journal article that you can find at a nearby library.
