My local library has an excellent selection of Christian fiction from the major publishers. A lot of it is in the paid section ($3 for two weeks, instead of free for three weeks). It might cost, but the cost still represents a saving over buying the paperback myself—most new releases cost between $25 and $30.
I used to visit the library most weeks. This was partly to feed my own reading addiction, and partly in an attempt to institutionalise and indoctrinate my children give my children a love of reading (I have a 50% success rate on that).
But the children got older, and I got a Kobo ereader, followed by a Kindle.
I found some of the books I was paying $3 for at the library were as cheap or free on Amazon. And I discovered NetGalley, which gave me free ebooks from many of my favourite authors if I reviewed the books. My library visits have gradually dwindled to nothing, even though they now offer free ebook loans as well as the traditional print books.
Why? Because I have more than enough to read at home between my physical print and virtual Kindle to-read piles (files?).
