资源简介：
Test dataset using Seattle Open Data's Checkouts by Title dataset as a structural example.
Coverage: checkout years 2020-2026.
Confidentiality protection: rows with fewer than 5 monthly checkouts at the title level are not published as distinct titles. Instead, those rows are reassigned to the title value "OTHER" and aggregated within the same usage class, checkout type, material type, checkout year, and checkout month. This reduces the risk of exposing borrowing patterns for rarely checked out items and also substantially reduces the overall dataset size.
