How many smell profiles have VERIFIED evidence

Open research questions

For every profile without a VERIFIED claim, SmellBook records one open research question: what kind of source could support a narrow statement about that smell. The agenda lists open research questions, not findings. It names no sources and makes no claim; an answer enters SmellBook only through source intake with a checked citation and classified rights. The agenda data lists entries alphabetically by line and entry; that order, like any order on a page, is not a priority or importance ranking.

Open questions by kind of evidence sought

• Aroma chemistry: 9 open questions (scientific evidence sought)
• Material emissions: 15 open questions (scientific evidence sought)
• Smellscape documentation: 27 open questions (cultural evidence sought)
• Atmospheric and environmental science: 1 open question (scientific evidence sought)
• Cultural and historical record: 3 open questions (historical evidence sought)

Searched; no suitable source found yet

55 of these profiles have been searched without finding a qualifying source yet: a source whose own text supports a narrow claim. Each search is listed with its date and reason in the agenda data. A recorded search found no source whose own text supports a narrow smell claim. It does not mean the entry is wrong, and it is not a score or ranking. The question stays open on the research agenda.

• 0 · Not researched yet: no search for a source has been recorded.
• 55 · Searched, nothing suitable found yet: each search is recorded with its date, the kind of evidence sought and the reason it found nothing.

Why searches have not found a source so far

Each number counts the profiles with at least one recorded search that ended for that reason. A profile can have several searches with different reasons, so these numbers add up to more than 55. They describe why searches have not found a source; they are not a priority order.

• 42 · The research found concerns a neighbouring subject, not this one.
• 14 · Studies measure this place or material, but report no smell or odour-relevant finding.
• 8 · A relevant source exists, but its text could not be checked or its rights could not be established.
• 12 · Only fiction or poetry describes this smell; no non-fiction source was found.
• 39 · No relevant study or record was found.
• 5 · The evidence found belongs to a related entry, which already cites it.
