Bookstores and libraries are public places. The only difference is that the bookstore is profitable, and you have to provide money to buy the books you like. The library is a public welfare machine operated by the government or schools.

A library is an institution that collects, sorts out and collects books and materials for people to read and refer to. The first library appeared in 3000 BC. Library has the functions of preserving human cultural heritage, developing information resources and participating in social education. At school, students can take part in book activities with their library cards, such as borrowing books from the library, taking them out of the reading room at will, or reading books in the reading room. But at the same time, you have an obligation to take care of these books, because they are not yours. If you damage these books in the process of borrowing, you must pay compensation at the same price or the price stipulated by the library. And return it to the library in time after the lease expires.

Bookstores use money to buy books you like. After the transaction, these books are yours, and you have no obligation to keep them.
