Many publishers are giving us temporary access to their resources so that users can work and study from home in the best circumstances.
We are given extra online content in the form of books, journals and databases by several publishers. This way users can hopefully find all the resources they need even though they can't go to the library anymore. This extra content is of a temporary nature however and will disappear again after the crisis.
Access is normally set up via IP recognition so you get automatic access from home when you use a VPN connection.
