Descriptions from the bioRxiv website below:
bioRxiv (pronounced “bio-archive”) is a free online archive and distribution service for unpublished preprints in the life sciences. It is operated by Cold Spring Harbor Laboratory, a not-for-profit research and educational institution.
Articles in bioRxiv are categorized as New Results, Confirmatory Results, or Contradictory Results. New Results describe an advance in a field. Confirmatory Results largely replicate and confirm previously published work, whereas Contradictory Results largely replicate experimental approaches used in previously published work but the results contradict and/or do not support it.
Readers may add public comments to articles on bioRxiv. Comments are moderated to ensure they conform to the standards of normal professional discourse. Readers are also free to contact authors directly.
All articles uploaded to bioRxiv undergo a basic screening process for offensive and/or non-scientific content. Articles are not peer-reviewed before being posted online. No endorsement of their methods, assumptions, conclusions or scientific quality by Cold Spring Harbor Laboratory is implied by their appearance in bioRxiv.
