In libraries, the classic version of TPMs would be electronic books. Unlike journals, most electronic books come with some type of technological protection measure, which in some cases prevents any printing or downloading entirely, so you can't exercise any fair dealing rights whatsoever, and you cannot send a chapter on interlibrary loan. You can't do anything with it; it's just completely locked down. They go from that to limiting printing or downloading to 1% or 5%.
