The “Peer Community in” (PCI, https://peercommunityin.org) is a group of scientific communities of researchers reviewing and recommending, for free, unpublished preprints in their field (i.e. unpublished articles deposited on open online archives like arXiv.org and bioRxiv.org). These specific communities are entitled Peer Community in X, e.g. Peer Community in Evolutionary Biology (PCI Evol Biol), Peer Community in Ecology (PCI Ecol), and Peer Community in Paleontology (PCI Paleo).
Preprints are submitted to a PCI by authors for an evaluation based on peer-reviews, eventually leading to a recommendation. Once recommended by one or several of these PCIs on the basis of rigorous peer reviews, preprints become valid references and may be considered to be articles of high value. Recommended preprints can be used by scientists and cited in the scientific literature. There is no need for these recommended preprints to be submitted for publication in classic journals (although they can be, according to the authors’ preferences). See https://peercommunityin.org
The community collection will gather articles peer-reviewed and recommended by a Peer Community In (https://peercommunityin.org) and ressources on PCI
