Quillhaven Libraries

Quillhaven Libraries is a fictional small municipal public library system built for BI teams that want credible civic operations data without enterprise-scale clutter or a forced revenue model. The system serves a mid-sized fictional town through a central library, four neighborhood branches, a bookmobile, and an online/digital branch. Its work is measured in community service: items circulated, cardholders served, holds fulfilled, and program seats filled. Overdue fines exist but are small and intentionally minor; this is not a sales dataset.

Operating Profile

• Runs 7 service points: a Central library, four community branches, the Quillhaven Bookmobile, and the Quillhaven Online digital branch.
• Maintains a representative catalog of about 900 items across eight formats and a range of fiction and nonfiction subjects.
• Serves about 28,000 registered patrons (roughly 19,700 active) across Adult, Youth, Senior, Student, and Educator card types.
• Circulates at item-checkout grain, tracks holds at reservation grain, and tracks programs at attendee grain grouped by session.
• Uses low-PII patron records only, with no emails, phone numbers, street addresses, payment cards, or government IDs modeled.

Recent Business Events

• 1Summer reading campaigns lifted children's and youth circulation and program attendance in both modeled years.
• 2The new Westgate community branch opened mid-window and steadily built circulation and program attendance, starting later than the established branches.
• 3Digital lending held about a quarter of circulation through the online branch, and eBook and audiobook hold queues ran deeper than the physical ones.
• 4Fall storytime and school-year programming created a second attendance bump each autumn alongside steady book-club and maker-workshop series.
• 5A handful of high-demand titles carried deep hold queues and longer wait days, while the long tail barely moved and weeded titles carry none at all.
