[IFLA] Modern creative industries have, to a large extent, built themselves on the basis of copyright. Their business models depend on having – or acquiring – rights to sell or use content, which they can then sell in exchange for remuneration. These rights are what lies behind the need to pay for initial access to a work. They are also the reason why, once a library or other user has legitimately bought or licensed a work, they may also need to pay extra in order to make certain uses of it... These payments can represent a source of revenues for creators and publishers. However, they also represent a cost to users.
