Walk backward from a strong paper

When it fits

• A strong recent paper uses terminology you did not know or sits in a topic that is hard to search by keywords.

When to avoid it

• Reference lists reflect author choices and can inherit citation bias; use citation searching as a supplement, not the only method.

Why it matters

Inspect the references behind the claims or methods that matter. Follow the most relevant cited sources to their original records and repeat selectively. Backward citation searching is especially useful when terminology changed over time or the concept is difficult to express in one query.

Steps

1. Choose a seed paper directly relevant to the question.
2. Identify the section whose evidence you need.
3. Inspect cited records supporting that section.
4. Open the original relevant records, not only the seed's paraphrase.
5. Add newly eligible records to the evidence map and terminology map.

Check your result

Backward searching finds relevant original or earlier evidence that keyword search did not surface.

Keep this limit in mind

• Reference lists reflect author choices and can inherit citation bias; use citation searching as a supplement, not the only method.
