# How to use The Longer Look

Long-form context and evidence-led reference.

## Start with a precise record

Use the name, identifier or place you want to investigate. The website scope is: Long-form context and evidence-led reference.

## Compare like with like

Open the relevant records and guides below. Keep identifiers, geography, units and source dates together; a record with a similar name or a different reporting period may answer a different question.

## Take the evidence to the original source

Follow the source references before making a consequential decision. Treat missing or historical information as a limitation, and use the relevant authority or provider for a current determination.
