Cross-Disciplinary Literature Search

Cross-disciplinary literature search is the research discipline of looking beyond one’s usual database, field vocabulary, or publication community before claiming novelty. In 47.鸟有什么好看的：原来…丹顶鹤是秃的！, [[KawakamiKazuto|川上和人]] initially treats crow blood-feeding as a potentially new biological finding, only to learn through review that similar behavior had long been known in livestock-related contexts.

The concept extends the wiki’s existing Medical Literature Search branch from professional access to search-boundary awareness. Finding no paper in the expected database does not mean the phenomenon is unknown; it may be filed under another discipline’s problems, terms, species, or economic concerns.

Key Claims

• Novelty claims depend on the search boundary, not only the search effort.
• Adjacent fields may know a phenomenon under different vocabulary.
• Reviewers can reveal that a discovery is new only in a narrower sense.
• Domain databases are useful but can create false negatives when the problem crosses fields.
• Cross-disciplinary search protects both scientific humility and claim quality.

Connections

• [[KawakamiKazuto|川上和人]] - crow-blood case.
• Observation Before Inference - evidence and claim discipline.
• Medical Literature Search - adjacent professional literature-access concept.
• Scientific Sampling Discipline - evidence quality before publication claims.
• Ornithological Fieldwork - field observation that triggered the search.
