What links these social centre projects together is the anarchist principle of self-management, which means they are self-organised and self-funding. They are anti-authoritarian and aim to show an alternative to capitalist modes of behaviour. However, there is no single type of social centre. The aims and policies of individual projects are determined by those running them and shaped by local contexts. This means that whilst every place is unique, functions will include some of the following: bar, bicycle repair workshop, café, concert venue, exhibition space, free shop, infoshop, language classes, meeting space, migrant support, radical library.
