BBC News Surface Observations

An independent longitudinal research dataset recording which stories appear on the BBC News front page and Most Read list, plus parsed snapshots of linked articles.

This project is not affiliated with or endorsed by the BBC. Headlines, article text, and linked content remain subject to the BBC's terms and copyright. The collection is published for research, audit, and journalistic analysis; users are responsible for ensuring their use is lawful.

Configurations

• observations: one row per story position and hourly collection. Stable story_id values make cross-surface and longitudinal joins straightforward.
• article_snapshots: parsed metadata and plain text fetched once per daily URL set. Raw HTML is kept in the companion raw dataset.
• scrape_runs: operational metadata for new collection runs, including selector version and validation counts.

All timestamps are UTC. Files use Zstandard-compressed Parquet partitioned by year, month, and UTC date. Schema version metadata is embedded in every file. Historical article fetched_at values are inferred from the old daily filename and are marked with fetched_at_is_inferred=true.

The migration audit at migration/manifest.json records source hashes, row counts, destination hashes, and the source Git commit.

Known limitations

• This records two BBC web surfaces, not editorial intent, readership, or all BBC output.
• Layout and selector changes can cause gaps. New runs fail closed if either surface is empty.
• The legacy article writer accidentally stored the URL in first_appeared_at; migration repairs it from the earliest matching observation when available.
• Front-page promos had no explicit rank historically, so their position is reconstructed from row order within each scrape.
