PeerJ is an Open Access, peer-reviewed, scholarly journal. It considers and publishes Research Articles in the Biological and Medical Sciences. It aims for rapid decision making and will publish articles as soon as they are ready.

Taking its inspiration from PLoS ONE, PeerJ selects articles based only on a determination of scientific and methodological soundness, not on subjective determinations of 'impact,' 'novelty' or 'interest.' It applies the highest standards to everything it does - specifically, the publication places an emphasis on research integrity; high ethical standards; constructive peer-review; exemplary production quality; and leading edge online functionality.

PeerJ Computer Science

As with the flagship biology and medical journal, PeerJ Computer Science is designed to select articles based on their scientific soundness only. It is both robustly peer-reviewed and Open access. More about this new journal can be found on the PeerJ Computer Science homepage.

Both PeerJ and PeerJ Computer Science operate a 'membership' model in addition to the traditional article processing charge (APC). The low-cost memberships give researchers rights to publish with us (for free). Unless paying via the APC route, all authors on a paper must have a 'paid membership' and there are 3 membership levels, each conferring different rights. The three memberships are: Basic (which allows for publishing once per year); Enhanced (which allows for publishing twice per year); and Unlimited (which allows for publishing an unlimited number of articles per year). Each membership also includes other benefits as laid out on the pricing page.

Authors can pay for a membership or APC at any point in time, however by the time of publication all Authors must possess a paid membership or settled their APC. Authors who choose to pay at submission get the cheapest rates for memberships, however authors can choose to submit for 'free' and pay only once accepted - in that instance their membership rates are slightly higher. 'No questions asked' waivers are available for authors from certain countries. Editorial decisions are made by independent Academic Editors based on the merits of each submission - in no way does the membership or APC status affect editorial decisions.

PeerJ and PeerJ Computer Science can accept submissions directly, or alternately via PeerJ Preprints. Papers can be of unlimited extent, contain unlimited color images, and can include supplementary materials, however surcharges do apply for substantially long manuscripts (email for more information). We encourage Open Peer-Review - specifically, reviewers are encouraged to identify themselves when submitting their reviews; and authors are given the option to post the full peer-review history of their submission alongside their published article (a policy which has been successfully pioneered by The EMBO Journal).

We believe that PeerJ will build a community of engaged scholars and that the community will collectively alleviate the burden of seeking and providing review comments. Therefore, a requirement of paid members is that each person must perform one review per year, or risk their membership lapsing. A review is loosely defined, and can be a comment, question, or answer to an article in PeerJ, PeerJ Computer Science, or PeerJ Preprints. Or a formal peer review on a submitted manuscript to PeerJ or PeerJ Computer Science (if qualified and invited). There are no annual commitments if opting for an APC payment for PeerJ or PeerJ Computer Science.

PeerJ Preprints is the 'pre-print' area of PeerJ. Similar to pre-print servers that already exist (for example arXiv.org), authors can submit draft, incomplete, or final versions of articles they are working on. By using this service, authors establish precedent; they can solicit feedback; and they can work on revisions of their manuscript. Once they are ready, they can submit their pre-print article into PeerJ (although it is not a requirement to do so).

PeerJ Preprints will only accept submissions in the same subject areas as PeerJ (Biological and Medical Sciences) and PeerJ Computer Science. In order to submit to PeerJ Preprints, at least the submitting author must have a user account with PeerJ. There is no pre-publication peer-review of submissions; however we reserve the right to introduce a basic quality filter. Submissions are made using the same platform as with the peer-reviewed journals, although some of the requirements are less stringent. Articles are not typeset, but we do provide automated conversion into PDF.

The default is for a PeerJ Preprints publication to be fully open to all viewers (what we call a 'public' pre-print).

All plans, including free plans, are able to publish unlimited public preprints.
