> It is also true that much content is “preserved,” often illegally, in shadow libraries/archives such as Library Genesis and Sci-Hub (for more, see Bodo´, 2018a, 2018b; Eve, 2022). These archives are at great legal threat of shutdown but have also proved surprisingly resilient. We do not, in this article, count material stored in such archives, even though it constitutes an additional storage location.
This just further proves that projects like SciHub are absolutely essential and must be protected at all costs. Nobody cares more about preservation of knowledge and culture than loosely organized groups of volunteers.
