- Read
- October 19, 2026, and again every month
- What it measures
- A count of papers, preprints, books and other scholarly works that use the phrase: a measure of research activity on the topic.
- How it is measured
- Once a month we ask OpenAlex, the open index of scholarly works, how many works per publication year mention each quoted phrase in their title, abstract or full text, and keep every year since 1990. Each fact is the last complete year.
- What it does not show
- OpenAlex keeps adding works, so recent years grow for a while after they end, and a phrase search counts any use of the words. Compare topics and years, not exact totals.
