Genrefying a library’s fiction collection is a common practice in school libraries. However,
there is little research to explain the benefits or drawbacks of this practice. Using a withinsubjects/time-series action research design, this study was conducted to understand more about
the impact of genrefying the fiction collection in a single library. This study found that
elementary students could locate fiction books faster and to greater satisfaction with a genrefied
collection than in a collection in which fiction was arranged in a FIC label format, which is
typically seen in standard Dewey Decimal classification.
