The Gigapedia electronic library, also known as Library.nu (LNU), lasted a total of about five years, after which it closed, to a large chagrin of its audience. The grief was caused, first of all, by the fact that there could be books that there were no books in other places (including in stores). In addition, it was a very large library (in official sources, the figures are mentioned about 400,000 books, in user comments - about 750,000).
