Paper mill

A commercial operation that produces fabricated or low-effort manuscripts and sells authorship slots, or that brokers acceptance of such manuscripts into journals. A submission originates from a paper mill if the underlying research was not conducted by the named authors or was fabricated to order.

Editorial commentary

Paper mills have shifted from individual hobbyist operations to industrial-scale enterprises producing thousands of manuscripts per year, often with shared figure templates, tortured phrases (from machine paraphrasing), and citation patterns that recur across unrelated venues. COPE and STM jointly published 'Paper Mills' (2022), and the United2Act initiative (2023) coordinates publisher, integrity-officer, and sleuth response. Detection signals include sudden submission spikes from the same institution, recycled figures across unrelated papers, and authors who cannot answer basic questions about their own methods.
