The North Liberty Library transitioned away from Dewey classification for nonfiction in 2011, switching to a modified BISAC (Book Industry Standards and Communications) or more commonly, the book store model. We get frequent calls about the process, how we got started, and what reaction has been from the public. The process continues to evolve over ten years after we started, and we've learned a lot along the way. Using this book store model eliminates a lot of confusion and mystery that surrounds the Dewey Decimal System, and hopefully presents a less biased approach to organizing a nonfiction collection.
