Richard Smith is the previous editor in chief of the BMJ. He has written an excellent BMJ blog post on a new "immediate publishing" academic journal called F1000Research.
1000Research, will post papers, including opinion pieces and case reports as well as clinical trials and other studies, within hours of them being submitted. If a study includes data then the authors must make it available—as the BMJ is now insisting on for clinical trials. With F1000Research the data will be available through the website. The data are citable, and the creators of the data will be credited when their data are used for new studies.
As the paper is posted it will be sent to reviewers who are asked to make one of three possible judgements: approved, approved with reservations, or not approved. Reviewers are encouraged to read papers quickly and to approve if the paper seems acceptable in that the conclusions are supported by the methods and data. (It seems to me that this can almost always be the case if the conclusions are suitably cautious.) If reviewers approve the paper then they don’t need to write anything but simply give it a green tick, which appears with their name on the website. Once a paper has two ticks it is indexed in Scopus and Embase and probably soon in PubMed and PubMed Central. Papers are being approved in days.
