Journal of the American Mathematical Society

The Journal of the American Mathematical Society (JAMS) is a premier peer-reviewed research quarterly published by the American Mathematical Society (AMS), dedicated to publishing research articles of the highest caliber across all areas of pure and applied mathematics. Its Journal Impact Factor (JIF) is the Clarivate-calculated metric tracking citations in a given year to citable papers published during the two preceding calendar years, contextualized by open bibliometric benchmarks including OpenAlex two-year mean citedness.

What Is the Journal of the American Mathematical Society?

Widely known in the international mathematics community as the jams journal, the Journal of the American Mathematical Society is published quarterly by the American Mathematical Society (AMS). Established to publish papers of outstanding significance and technical depth across all branches of the discipline, JAMS maintains exceptional editorial selectivity, accepting approximately 16 to 27 articles per calendar year. Research published in JAMS adheres to rigorous formal exposition, structured according to established mathematics paper writing conventions and theorem-proof structures.

Every paper in JAMS receives a permanent digital object identifier registered through CrossRef, facilitating persistent citation linking via its CrossRef DOI. The journal carries print ISSN 0894-0347 and online ISSN 1088-6834, with more than 1,380 persistent works cataloged in the CrossRef registry. The broad scope of the journal reflects core foundational areas examined in our overview of mathematics research areas and career paths.

Journal of the American Mathematical Society Impact Factor and Metrics

The journal of the american mathematical society impact factor is a proprietary journal-level metric published annually within Clarivate Analytics’ Journal Citation Reports (JCR). The traditional two-year Journal Impact Factor calculates the average citation frequency per citable item:

$$text{JIF}_y = frac{text{Citations in year } y text{ to items published in } (y-1) + (y-2)}{text{Citable items published in } (y-1) + (y-2)}$$

Because JAMS enforces an extraordinarily strict volume limit—publishing around 20 papers per year—its two-year citation denominator is small. Consequently, citations generated by a few major mathematical breakthroughs or Fields Medal-level papers can produce substantial upward pressure on annual two-year citation ratios. Researchers evaluating publication impact also review multi-year benchmarks such as the Elsevier Scopus CiteScore, which evaluates citations over a four-year window.

Open Bibliometric Benchmarks for JAMS

Open bibliometric platforms offer transparent, non-paywalled insight into JAMS’s scholarly reach. OpenAlex source data (Entity S130224168) records the following verified metrics:

Host Organization / Publisher: American Mathematical Society (AMS)
Standard Identifiers: ISSN 0894-0347 (print), ISSN 1088-6834 (online)
Cataloged Scholarly Works: 1,291 works
Cumulative Citations: Over 116,400 citations across indexed literature
Two-Year Mean Citedness: 19.81
h-index: 173 (with an i10-index of 1,074)
Annual Work Output: Approximately 16 to 27 articles annually (e.g., 20 articles in 2025, 27 in 2026)

These figures demonstrate that despite publishing fewer than 30 papers per year, JAMS receives over 5,500 citations annually across the scientific literature.

Responsible Research Assessment in Pure Mathematics

While JAMS’s metrics reflect high community esteem, academic bodies caution against treating journal-level metrics as direct evaluations of individual researchers. Under the San Francisco Declaration on Research Assessment (DORA) and the Coalition for Advancing Research Assessment (CoARA), institutions are committed to qualitative evaluation of mathematical substance rather than relying on a venue’s Journal Impact Factor.

Pure mathematics research often exhibits long citation half-lives, where foundational theorems may take decades to accumulate their primary citations. Using short-window journal metrics to judge tenure, promotion, or grant allocations risks penalizing deep, foundational scholarship in specialized fields.
