That attachment might be something to work on. I wouldn't mind stimulating my kid to build up their own library once they've reached the point of reading adult fiction and books can be reread by themselves after a few years, or enjoyed by others in the household. But at her age the library is perfect. Most of the books they read at that age are of transient value.

Alternatively, take her to second hand book fairs and stimulate bargain book hunting in charity shops.
