- Public holdsPublic holds: BPL exposes 'people waiting' at the bib (record) level — one number per work for the entire 60+ branch BPL system, NOT just the 12 tracked branches. We capture the number when it's there. 'Not exposed' means BPL didn't expose it on this scrape — we never substitute zero for missing data.
