Some changes have taken place in the library. More and more people borrow books from the library, not physical books, but e-books that can be read on Kindle and mobile phone tablet. Not only that, music, games and movies can be obtained from public libraries for free.

These digital services make more and more people get into the habit of borrowing e-books and movies from the library, but the publishing mode of e-books is actually different from that of physical books, which also makes the library's e-book borrowing service face some problems that will not appear in the past.

According to the agreement signed between the e-book publisher and the library, each digital book cannot be lent to many people at the same time, and each book has a limited number of times of borrowing. If it exceeds this amount, the library will buy it again. In addition, the library does not enjoy the ownership of these e-books, but only purchases reading licenses, which means that content providers can delete or remove these e-books at any time.

In fact, e-book publishers do this to protect their own interests, because the number of each set of physical books in the library is limited, which generally will not affect the sales of physical books. Once the e-books obtained online are open for reading, it is likely to affect the income of e-book publishers. After all, in big cities like LA and new york, public libraries have tens of millions of users.
