Gawrylewski A. 2007. New site pits 'published' vs. 'posted': Nature Precedings raises questions over the value of sharing findings before submitting to peer review. The Scientist. 19th June
Nature set up a new site, named "Nature Precedings", to post pre-print articles which are not yet submitted to the peer review. This is a kind of experiment to be interestingly watched, particularly with respect to the consequences on scientific communication, publishing and evaluation aspects.
