Don't say it's the original, 90% hope the content of this book is ok. Nowadays, many writers don't write by hand, but type or input by hand. Therefore, we see more and more e-books. If these e-books sell well, the author will consider publishing them. Therefore, even if these books in the library are gone, we will not be afraid.
In the future, with the development of AI technology, the wisdom of robots is endless. It is also a good idea to let the robot browse books that have not been compiled into electronic data and put them in the robot's memory. If you lack that book, you can extract it from the robot, and the boy will print and publish the whole set. This is a very convenient method, and today's high-tech methods are not only that. As soon as the text is scanned by technical means, a large amount of data will appear in the document. Once these documents are printed, they will be a brand-new book. I think as long as the books in the library are managed and the electronic files are preserved in the early stage, no matter how many times the books in the library disappear in the later stage, they will be restored with human wisdom and ability.
With the popularity of the Internet and the diversification of electronic products, many books can be read without going to the library. However, most of the excellent data are not made public, mainly because they are too valuable and need to be paid to see. Now people who pay online can also read e-books, mainly because most people like to read the paper version. So the popularity of electronic documents is low.
