By signing the Barcelona Declaration, VU Amsterdam commits to four principles:
1. open research information becomes the norm
2. (collaborate with) services and systems that support and enable open research information
3. support sustainable infrastructures for open research information
4. collaborate on the transition from closed to open research information
The University Library has already taken a number of steps that contribute to these principles, and is working on further steps. For each of the four principles, these are described below.
