Chat Away

PubMed Commons has opened up further to the community, Sally Rockey, the deputy director for extramural research at the US National Institutes of Health, writes at the Rock Talk blog.

The forum and post-publication review system launched earlier this year as a pilot version open to invited participants. About a week after its launch, the National Center for Biotechnology Information noted that 1,000 had signed up and about 100 comments had been made. About half of those comments, NCBI said at the time, were back-and-forths about the paper, while others provided updated links to databases or other corrections. The PubMed Commons blog notes that several hundred comments have now been made.

Rockey adds that commenting is still limited to authors of publications found in PubMed, but the public can now see those discussions.
