I’m a member of two libraries, a result of having a home in one city while living in another.
I tend to use the library to read books from new-to-me authors, or books from authors I’m happy to read once. If I think I’ll want to re-read a book, I’m more likely to buy it on Kindle than borrow it from my library … and that includes most Christian books.
My home library has a lot of adult Christian fiction, including new releases, so I’ve never needed to request any.
I did request a few Christian children’s books once – books in a series my daughter had borrowed and read – but the library said the books she had already read weren’t borrowed often, so they weren’t going to buy the rest of the series.
My local library has some Christian fiction on the branch shelves and more available for request from the offsite storage. It’s mostly new releases, and I haven’t yet worked my way through the titles they have so haven’t requested they buy any.
it’s typically hard for me to find Christian books where I’m located so I always have to request them. Usually they get some within a few weeks.
