Off the Books, Not Off the Shelf

Validating a Library Book-Swap Shelf's QR Circulation Tracker Against a Term of Twice-Daily Physical Counts

A research poster from the School of Continuous Improvement audits the Library's book-swap shelf, matching 196 physical shelf counts against its QR scan-in/scan-out tracker's circulation log across a 14-week term. Physical turnover holds steady (median 33.5 books/week) while the tracker's own capture rate falls from 61% to 9%, tracking the condition of its shelf-edge stickers rather than the shelf's actual use.
