Public Domain Calendar & Archive organizes records from Open Library APIs and data into a static table for transparent comparison. It preserves official source links and dates, marks missing enrichment, and adds deterministic grouping, change, recency, trend, or significance fields only where the documented inputs support them, without recommendations or unsupported claims.
