Data Sources
Incoming Science aggregates content from the following sources. We are grateful to each for making open access to scientific literature possible.
Preprints
arXiv — Cornell University
Daily preprint feeds across physics, mathematics, computer science, quantitative biology, economics, and related fields. arXiv is the primary source for new papers in most fields covered by Incoming Science.
bioRxiv — Cold Spring Harbor Laboratory
Daily preprint feeds across biology and life sciences, including systems biology, bioinformatics, and genetics. bioRxiv papers are routed to the same triage pool as arXiv papers for fields that cover biological topics.
medRxiv — Cold Spring Harbor Laboratory
Daily preprint feeds covering clinical medicine, epidemiology, and health sciences.
NBER Working Papers — National Bureau of Economic Research
Working paper feed covering economics, finance, and public policy research.
CEPR Discussion Papers — Centre for Economic Policy Research
Discussion paper feed covering economics and public policy, with a strong European perspective.
Journal Publishers
American Physical Society (APS)
RSS feeds and full-text abstracts via the APS Harvest API, covering Physical Review Letters, Physical Review B, Physical Review X, PRX Quantum, and Physical Review Applied.
Nature Portfolio
RSS feeds from Nature, Nature Physics, Nature Communications, Nature Photonics, Communications Physics, npj Quantum Materials, npj Quantum Information, and other journals in the Nature family.
AAAS / Science
RSS feeds from Science and Science Advances.
IOP Publishing
RSS feeds from New Journal of Physics, Journal of Neural Engineering, and other IOP journals.
American Chemical Society (ACS)

SciPost
Open-access RSS feeds from SciPost Physics and its specialised section journals.
Additional publishers
Wiley, Springer, Oxford University Press, Cambridge University Press, SAGE, Taylor & Francis, Cell Press, PLOS, AIP Publishing, EDP Sciences, and Elsevier — providing RSS feeds across social sciences, biology, and interdisciplinary fields.
Abstract Enrichment
For journal articles whose full abstracts are not available in their RSS feeds, Incoming Science queries the following open scholarly databases to retrieve them.
Semantic Scholar — Allen Institute for AI
Batch API used to retrieve abstracts for journal papers not directly accessible via RSS, including ACS journals. Semantic Scholar indexes hundreds of millions of scientific papers across all disciplines.
OpenAlex
Open catalog of scholarly works, authors, and institutions. Used as a fallback abstract source for papers from publishers with restricted access.
CORE
Aggregator of open-access research outputs from repositories worldwide. Used as an additional fallback for open-access papers not yet indexed by other sources.
