Seasoned readers know where to look for their digital favourites: in the libraries. Libraries usually buy a book once, and anyone who is a member of the library can read that book. Let’s see some ways publishers can ensure to keep their profits high while not losing out on readers.
Libraries may buy a book permanently, for a limited period (‘expiration date’) or for a certain number of checkouts. If this happens, libraries often pay a higher price, multiplying the digital list price.
Another possible model is pay per use: for example, 10% of digital list price for 21 days. If your book is priced at 10 USD, you get 10% of $10.00 = 1 USD for a 21-day loan. After the 21 day period, the title must be repurchased for another 21 days. This option allows librarians to meet a short-term demand for a popular title without having to overburden their budgets or turn patron away if their ‘permanent collection copies’ are already borrowed.
