Cool, yeah I know the sorts of books you mean. And agreed that the authors do not write those chapters in the expectation of royalties and agreed one shouldn't feel guilt in pirating them. But your post is at risk of being read out of context, as saying that libgen should be used without guilt, and there are people in this thread who seem almost to think that there are no ethical questions surrounding libgen, and who seem to think that libgen is ethically equivalent to scihub.
