The document discusses how the Portneuf District Library in Chubbuck, Idaho redesigned their nonfiction section by creating their own subject headings that better reflected their community. They weeded over 2,000 books, heavily relabeled their collections section by section over 8 weeks, and saw a 250% increase in nonfiction circulation and a 90% overall circulation increase as a result. The redesign was well received by patrons and staff. They plan to next redesign their fiction section using a similar approach.
