Sounds like you have a crappy library in your town. My town's library is linked with all of the other libraries in my county. Books can be requested and shipped to my home library within a couple of days. This has lead to librarians working together and "specializing" in certain materials. All of the libraries have a good selection of popular material.

My library tends to have a larger non-fiction section than most. Another town houses a huge collection of movies. Yet another hosts a tremendous audiobook collection. A simple online request will deliver any of these materials nearby or I can wander in and browse if I'm looking for something more mainstream.

Perhaps you should consider getting more involved if your library isn't meeting your needs.
