It makes sense that you can use it whenever. In order to meet the needs of users, it should be accessible in the same way the library is accessible. If it’s only available as prescribed events then that would be easier to control but it wouldn’t put creativity and innovation firmly with the users at the centre. As a service, it should be widely and easily accessible. I think to market something like that they’d need to try to run some programs to get people in and aware of it, and then hopefully it will gain traction in the community as a space people can use. I’m curious to know where this is, because none of the libraries near me have makerspace services (only limited programs at set times) and I’d love to visit if it wasn’t too far away.
