The library of Alexandria famously copied every book that that entered the port of Alexandria. Libraries 'buying not copying' is a modern mode of operation, but not intrinsic to the premise of libraries.
That first lowercase "library" formed a garden path that reminds me: How (nearly) nominatively deterministic of Elbakyan! In a way your comment makes sense there too, when considering Sci-Hub's purported use of donated credentials.
Hope the next Alexandria library is named Elbakyan library. She surely deserves. And this time I hope it doesn't catch fire. Fortunately bits are not as flammable as paper. But on the other side they are higher maintenance to last thousands of years.
