2. Newspapers and magazines are for personal short-term reading, and lending the library will affect others' reading because of its time limit.
3. The old books were taken down from the shelves. Some books that lack reading value for a long time will be removed from the shelves to save shelf space. Old books are piled up in dense piles, so we don't lend them out.
There are some special books in the library, such as reference books, maps, encyclopedias and Ci Hai. Just buying a few books is expensive and cumbersome, and it is not convenient for readers to borrow them. Some people may only buy a book, but if you lend it out, others can't read it, and generally don't lend it to readers to look it up in the library. It also includes non-paper materials such as CDs, tapes, films and microfilms, which are also not lent out.
