Bit of a random one but...
My local library heavily promotes an eBook borrowing service. But eBooks are never available. I've tried searching for 10 books today, but none are available for months - and one of them has a 450 person hold waiting list!
Also why is there only one copy of an eBook? Surely if it's digital it can be read by different people at the same time, and surely would be a significant point of having eBooks? Also seems like it would be a struggle for people with visual impairment to ever borrow anything?
