PLoS ONE

PLoS ONE is an open access peer-reviewed scientific journal published by the Public Library of Science since 2006. It covers primary research from any discipline within science and medicine. All submissions go through an internal and external pre-publication peer review but are not excluded on the basis of lack of perceived importance or adherence to a scientific field. The PLoS ONE online platform has post-publication user discussion and rating features.

Development
PLoS ONE was launched in December 2006 as a beta version. It launched with Commenting and Note making functionality, and added the ability to rate articles in July 2007. In September 2007 the ability to leave "trackbacks" on articles was added. In August 2008 it moved from a weekly publication schedule to a daily one, publishing articles as soon as they became ready. In October 2008 PLoS ONE came out of "beta". Also in September 2009, as part of its "Article-Level Metrics" program, PLoS ONE made the full online usage data for every published article (HTML page views, PDF, and XML downloads) publicly available.

Output
In 2006 the journal published 138 articles; in 2007 it published just over 1,200 articles; and in 2008 it published almost 2,800 articles, making it the largest open access journal in the world. In 2009, 4,406 articles were published, making PLoS ONE the third largest scientific journal in the world (by volume) and in 2010 6,749 articles were published, making the journal the largest in the world (by volume).

Management
The founding managing editor was Chris Surridge. He was succeeded by Peter Binfield in March 2008.

Publication concept
PLoS ONE is built on several conceptually different ideas compared to traditional peer-reviewed scientific publishing in that it does not use the perceived importance of a paper as a criterion for acceptance or rejection. The idea is that, instead, PLoS ONE only verifies whether experiments and data analysis were conducted rigorously, and leaves it to the scientific community to ascertain importance, post publication, through debate and comment. This, however, is not always achieved in practice since editors and reviewers might have a subjective opinion about the articles they are reviewing which in turn might lead to the acception or rejection of papers of doubtful quality or intent. Each submission will be assessed by a member of the PLoS ONE Editorial Board before publication. This pre-publication peer review will concentrate on technical rather than subjective concerns and may involve discussion with other members of the Editorial Board and/or the solicitation of formal reports from independent referees. If published, papers will be made available for community-based open peer review involving online annotation, discussion, and rating.

According to Nature, the journal's aim is to "challenge academia's obsession with journal status and impact factors." Being an online-only publication allows PLoS ONE to publish more papers than a print journal. It does not restrict itself to a specific scientific area in an effort to facilitate publication of research on topics outside, or between, traditional science categories.

Papers published in PLoS ONE can be of any length, contain full color throughout, and contain supplementary materials (such as multimedia files). Reuse of articles is subject to a Creative Commons Attribution License, version 2.5. The journal uses an editorial board of almost 1,400 academics and in the first four years following launch it made use of over 35,000 external peer reviewers. PLoS ONE publishes approximately 70&thinsp;% of all submissions, after review by, on average, 2.8 experts.

Business model
As with all journals of the Public Library of Science, PLoS ONE is financed by charging authors a publication fee. The "author-pays" model allows PLoS journals to provide all articles to everybody for free (open access) immediately after publication. As of July 2010, PLoS ONE charges authors $1,350 to publish an article. It will waive the fee for authors who do not have sufficient funds. This model has drawn criticism, however. Richard Poynder argues that journals such as PLoS ONE that charge authors for publication rather than charging users for access may produce a conflict of interest that reduces peer review standards (accept more articles, earn more revenue). Stevan Harnad instead argues for a "no fault" peer review model, in which authors are charged for each round of peer review, regardless of the outcome, rather than for publication.

Community recognition and citation information
In September 2009, PLoS ONE received the Publishing Innovation Award of the Association for Learned and Professional Society Publishers. The award is given in recognition of a "truly innovative approach to any aspect of publication as adjudged from originality and innovative qualities, together with utility, benefit to the community and long term prospects". In January 2010 it was announced that it was to be analyzed by Journal Citation Reports. Its 2010 impact factor is 4.411. Additionally, the Scopus Journal Analyzer reports a "trend line" (total citations to all articles ever published received in a year divided by total number of articles published in that year) value of 3.74 for PLoS ONE for the year 2009 (up to February 10, 2010).

A number of Nobel Laureates have published studies in PLoS ONE, including Françoise Barré-Sinoussi, Elizabeth H. Blackburn, Jack W. Szostak, Oliver Smithies, and Barry Marshall.

In January 2011, Nature Publishing Group announced a competing journal, which many have claimed to be conceptually similar to PLoS ONE,  named Scientific Reports. According to the press release :

Scientific Reports will publish original research papers of interest to specialists within a given field in the natural sciences. It will not set a threshold of perceived importance for the papers that it publishes; rather, Scientific Reports will publish all papers that are judged to be technically valid and original. To enable the community to evaluate the importance of papers post-peer review, the Scientific Reports website will include most-downloaded, most-emailed, and most-blogged lists. All research papers will benefit from rapid peer review and publication, and will be deposited in PubMed Central.
