Ds's nursery takes all the 3 & 4 year olds to the library once a week. We also take him a couple of times a month.
I worked in bookshops for years and got out of the habit of visiting the library (pesky staff discount
. When I went back I got that "all these books! I can take them home! And it's free!" feeling that I had as a child all over again.
We can reserve books online, check the stock of all the city's libraries and have books transfered to out local library, put in requests for the library to buy books - all free.
Yes, Amazon is cheap but libraries are free! (for now)
I'm a medical librarian and we fully expect the government's baleful eye to seek us out sooner rather than later. As one senior administrator said when asked to approve our budget one year "Why does the hospital have to spend this ridiculous amount of money on magazines?" *
(*They were, of course, medical journals)
