Unlike the Dickens and Brontë memorabilia, which could just as easily be enshrined elsewhere, these are once-mundane objects you’d never find in a museum, but they’re an important part of our written culture and well worth saving. The library collects millions of such items — things, and to store and properly display things, you need a place in the world (preferably climate controlled), not just bytes in the cloud. Every human community creates such materials, and they all need libraries to preserve them.
I have to admit (shyly) I get a bit frustrated that all the people who defend libraries seem to feel the need to put them at opposition to digital mediums. Digital information is always ‘just bytes in teh cloud’ - insignificant in comparison :/
