Since 2007, a handful of public libraries across the United States have replaced Dewey Decimal Classification with a "bookstore arrangement" in order to meet the needs of users who have demonstrated browsing preferences. This paper looks at the implementation of BISAC-based headings used to arrange the collections at the Maricopa Library District in Arizona, the Rangeview Library District in Colorado, and the Frankfort Public Library District in Illinois. A multi-methods approach was employed: 1.) a content analysis was conducted to analyze the availability and characteristics of BISAC headings and to provide a sample of headings taken from the online catalogs of the three aforementioned library districts, and 2.) an evaluative survey was distributed for participants to evaluate the BISAC-based headings. The fifteen participants, a mix of both users and librarians, indicated that they favored headings that were more specific, however, there is a need for continued research on the use of BISAC headings to arrange the collections of public libraries
