The field of biology does not yet make extensive use of preprints as a medium for distributing new research. Two preprint gateways are Stanford's Preprints and Working Papers and the U.S. Department of Energy's PrePRINT Network. On the DOE page, choose Subject Pathways for listings of full-text preprint sites by subject.
Two areas of continuing interest to Middlebury biology students are phylogeny and biodiversity and genetics. Below are some useful websites.
