I think libraries are an essential part of any civilised society, and I for one will be furious if they start closing them. :(
I would volunteer to help keep my local library open IF that was the only option, but I would far rather that it was properly run by trained, qualified staff. In my view, the service would suffer greatly if that ceased to be the case.
Unfortunately, I'd only be able to volunteer at weekends, and then probably with dd in tow. I suspect we'd end up with severely restricted opening hours if this stupid policy was actually followed through. I keep hoping, though, that the idiots in charge of the country will eventually come to their senses and realise that this just ain't gonna work!
