Map scientific literature without confusing proximity with evidence
Paper maps help explore relationships but establish neither study reliability nor exhaustive review coverage. Litmaps and ResearchRabbit document discovery workflows; inclusion decisions still need explanations.
The method to apply
Define a question, select several seed papers and compare two discovery paths. Retain identifiers, versions, inclusion reasons and reading results for each accepted reference. Proximity or citation frequency does not automatically establish evidence.
- Relevance
- Identity
- Diversity
- Traceability
Prepare, test and decide
1. Bound the question
Specify domain or population, phenomenon, period and eligible study types. Define exclusions before viewing results so the map does not silently redefine the scope.
2. Diversify seeds
Choose papers identified in your own research, alongside a different approach and recent work where relevant. One seed may confine discovery to one community.
3. Open references
Check DOI, title, authors, year and version against the publication. Distinguish preprints, revised papers and corrections. Do not include an entry solely because its abstract appears relevant.
4. Inspect relationships
Record whether each connection represents citation, calculated similarity or recommendation. Nearby papers may use incompatible methods or reach opposing conclusions.
5. Keep a decision table
Retain identifier, covered question, method, limitations and include, exclude or reread decision. Explicit reasons let you revisit choices without repeating discovery.
6. Check blind spots
Search alternative terminology, contrary findings and known references missing from the map. If a systematic review is required, follow an appropriate protocol rather than declaring the map exhaustive.

Put the method to work
Practical case
For a non-sensitive research question, build two maps with three different seeds.
Evidence to keep
Keep seeds, five discoveries per map, DOIs, versions and inclusion reasons.
Make the decision
Include relevant papers after reading and explain omissions; do not present this exercise as a general tool benchmark.
Acceptance criteria
Relevance
The paper answers the bounded question.
Identity
DOI and version match the read document.
Diversity
Several seeds and discovery paths are examined.
Traceability
Exclusions retain reasons.

Frequently asked questions
How many seeds are required?
There is no universal number. Diversify approaches relevant to the question and inspect omissions.
Does a map replace reading?
No. Reading the document and its limitations determines which claims it actually supports.
The references below expand on the concepts and checks discussed. Scenarios and trial frameworks remain editorial proposals; provider documentation describes its own product rather than an independent benchmark.
