The difference between traditional library and digital library

Traditional library is an organization that publishes physical documents, which have many carriers and require readers to enter the library to get services. Digital library digitizes the contents recorded in various carrier documents, then organizes publishing, spreads through the network and uses computers. The biggest difference is that the digital library can only provide knowledge of document content, while the traditional library can not only provide knowledge of document content, but also study the technical level and version at that time according to document carriers, such as paper and film. In addition, at present, the document content provided by digital library is not as good as paper books and maps when dealing with charts (especially scanned large charts), such as Baidu and Google maps you see, which will be limited by the size of computer screen, but the wall chart doesn't matter. In addition, some design books are not as good as paper, so you can measure them with a ruler (poor intuition). Moreover, the library is an individual, and the digital library is a collection (currently defined as a digital library). If you want to know more, you can borrow books from the library to study.
