I am not a librarian. Yet. If ever. But I am thinking about it more and more.
I want to show you a device that you ought to be aware of, you should know that the traditional book isn't going gently into the dust. But it might be transformed.
This is especially important for fragile or extremely old materials. They wouldn't stand up to this type of processing; there are gentler scanning methods for the at risk materials.
This is an just one small example of how that change is going to happen. I'm not endorsing any specific product. I literally walked up to this one and hit record.
