View Wiki Version: [(Current) Reese Richardson: 2025-06-13 14:06:19+00:00 UTC] ![COSIG Logo][1] ### **Anyone can do post-publication peer review.** ### **Anyone can be a steward of the scientific literature.** ### **Anyone can do forensic metascience.** ### **Anyone can sleuth.** However, investigating the integrity of the published scientific literature often requires domain-specific knowledge that not everyone will have. This open source project is a collection of guides written and maintained by publication integrity experts to distribute this domain-specific knowledge so that others can participate in post-publication peer review. COSIG currently hosts 28 guides and was last updated on 13 June 2025. Guides can be downloaded as [individual PDFs](https://osf.io/2kdez/files/osfstorage). A combined PDF with all guides included can be downloaded [here](https://osf.io/ynb8j). Suggestions to improve COSIG can be submitted by opening an issue on [COSIG's GitHub repo](https://github.com/cosig-pppr/cosig/issues) or by emailing [admin@cosig.net](mailto:admin@cosig.net).
