Covering biology, medicine, chemistry, and earth sciences, Nature Precedings is an repository for scientists and researchers to deposit and share pre-publication research, unpublished manuscripts, presentations, posters, white papers, technical papers, supplementary findings, and other scientific documents. Submissions are screened, but are not peer reviewed. Nature Precedings may be browsed or searched, and RSS feeds and email alerts are available for several subjects. Developed by Nature Publishing Group.
Access is provided to biology and medicine preprint collections or preprints provided by individual authors.
viXra.org (reverse of arXiv) is a preprint archive alternative. It places no restrictions on the sorts of papers that can be posted.
