We have gone to many of the local libraries here and I just wasn't finding a large enough selection for my tastes, so we travel to Raleigh, which is about an hour away and joined their library system. The cost was $25 for a year, which I think is affordable.
We go up either weekly or every other week and it is a family night affair. We spend all the time we wish at the library and then have dinner at a favorite deli or Mexican restaurant.
We each get our books according to the book list I listed previously and the time period they are studying. It keeps us organized. We also try to get a few audio books as well.
