PsyArXiv (psychology archive) is designed to facilitate rapid dissemination of psychological research. PsyArXiv is a creation of the Society for the Improvement of Psychological Science (SIPS) and the Center for Open Science (COS).
PsyArXiv allows scholars to post documents such as working papers, unpublished work, and articles under review (preprints), making them accessible to other researchers and to the public at no cost. Users can also upload revisions of their posted document and supplemental documents such as appendices.
Most journals in psychology permit posting of preprints, and for most journals you can find their policy at the SHERPA/RoMEO database. Before publication, articles are your creative product to do with as you please. If your article has already been published in a journal, be sure to check the journal policy on posting — for example, many do not allow posting of the publisher-prepared PDF, but do allow posting of the original author-formatted document.
PsyArXiv’s infrastructure is provided by the Center for Open Science which also allows simultaneous search of PsyArXiv with other preprint services. Additional existing and coming capabilities for PsyArXiv can be found at the roadmap.
