I’m jatta Shankar from india and i am highly dependent for the book and materials on your website. Realistically, when all copies of a book on the library’s bookshelf are borrowed, the next patron try to borrow it have to wait until any of those copies are returned = when the number of copies of an e-book the digital library legally owns is also the number of people currently borrowing it, results the next person having to join the waitlist until any of the currently digitally-borrowed books are returned (either the other borrowers manually return it or the DRM auto-returns it)Physical books can be illegally snapped by a camera by a patron = the same act can be done on an e-book displayed on a device’s screen. OpenLibrary keeps out of print books available foreverInternet Archive is an incredibly important site
