Peer Community in … A free recommendation process of scientific preprints (and published articles) based on peer-reviews (photo credit: Ben Lee, Stockholm library)

"The “Peer Community in” (PCI) is a non-profit scientific organization that aims to create specific communities of researchers reviewing and recommending, for free, unpublished preprints in their field (i.e. unpublished articles deposited on open online archives like arXiv.org and bioRxiv.org). To a lesser extent, they may also recommend postprints (i.e. articles already published in journals)."
