It is heartening to note that 200th article from PLoS ONE has now been evaluated at the Faculty of 1000 Biology. Last year on July 17, a report on the evaluation of 100th article from PLoS ONE was posted on this blog. It is about in a year's time that further one hundred articles were evaluated; a remarkable achievement despite a very high volume publishing in diverse areas. Since the number of articles almost tripled in a year (6000 in August 2009 versus 2600 in July 2008), the number of evaluations touched almost 10 per month (3.3% of total articles published). For a broad based and high volume journal such as PLoS ONE, the F1000 evaluations serve as an important quality index for individual articles.
