The project in a few lines


The first Peer Community in has been launched in 2017: Peer Community in Evolutionary Biology

Coming in late 2017 or 2018: PCI Ecology, PCI Paleontology and PCI Computational Statistics

More than 300 recommenders have already joined Peer Community in Evolutionary Biology.  Visit its website :


The “Peer Community in” is a non-profit scientific organization aimed at creating specific communities of researchers reviewing and recommending preprints (and also published articles) in their field. These specific communities are entitled Peer Community in X, e.g. Peer Community in Evolutionary Biology, Peer Community in Ecology, Peer Community in Computational Statistics.

Becoming a recommender

Becoming a recommender of a Peer Community in X would not be associated with a substantial workload. Recommenders organize the peer-review process of preprints and may recommend them. They would handle less than 2 articles per year in average.


The motivation behind this project is the establishment of a high-quality, free, public system for identifying high-quality preprints by a specific recommendation obtained after peer-reviewing. This system would be recognized within and subsequently beyond the community, including by funding and research agencies.

This project should lead to a new scientific publication system, in which preprints are deposited in open and free archives, and if appropriate, reviewed and awarded a recommendation publicly guaranteeing their scientific quality. This recommendation could replace the current evaluation and editing process of scientific journals, which is often opaque and very costly for research institutions.


The non-profit “Peer Community in” organization is responsible for the creation and the functioning of the various specific Peer Communities in X.

Each Peer Community in X will include an unlimited number of recommenders appointed by its Managing board. These recommenders would recommend after peer-review preprints deposited on open online archive sites (e.g. bioRxiv) (or published in scientific journals). The Managing board of a Peer Community in X will be constituted by a limited number of persons chosen among the recommenders of this Peer Community in X and they will be regularly replaced.

The Managing board members of each Peer Community in X will also be members of the non-profit “Peer Community in” organization. Hence, representatives of all existing Peer Communities in X would decide the creation of new Peer Community in X collectively.

The recommending process

The recommendations attributed to preprints, and the peer-reviews leading to their attribution, would be posted and freely readable on the website of the Peer community in X concerned and widely publicized through social networks. Each recommendation would provide a link to the internet location of the corresponding preprint (either a DOI or the Internet address at which the paper was deposited).

  1. This is a very good initiative. I have a question about becoming a reviewer. The information provided on this website states that reviewers can be nominated by current members of Peer c.i. or propose themselves, but whatever the process they are to be approved unanimously by the managing board. To be a reviewer one should actively be doing scientific research and(or?) be known for one’s pertinent reviews. As much as I think that your idea is great, it sounds a bit like an exclusive club, just the sort of thing that we all hope we could move away from. Many of us just want to discuss science for the value of the ideas and as means to solve problems and we don’t (and perhaps shouldn’t) care who is speaking in the debate. The description of the Peer c.i. system also makes me wonder if there will be any monitoring of the reviews written by the reviewers before they are posted or if the reviewers have free reign once they get approval.
    I was wondering why you did not opt for a system where anyone could be a reviewer, and then before reviews were posted they were checked by the Reviewing Board for deployment of reasoned and founded arguements, for objectivity, for an obvious lack of vengence or trashing, and that they were overall scientific.


    1. Many thanks for your comments. It is true that we did not retain the option of a fully open Community. We preferred a system in which members of the Peer Community in X are appointed by the Managing board and in which any researcher can be punctually solicited by members of the Community to review a MS. The main reason is that we want Peer community in recommendations to be based on reviews of high quality. Our goal is therefore not to be an exclusive club, but merely to ensure that each member of the Peer Community in X is recognized by the peers as good enough in his/her field of research to perform sound recommendations. This is important since nobody will check the quality of the reviews underlying those recommendations (see below).
      Another important reason is that we expect that members of Peer community in X will act as members of a community that matters for them. Because members will be nominated by the community, they will probably be particularly motivated to perform very good reviews and to follow a code of ethical conduct (no conflict of interest, no recommending of articles published by recent co-authors and/or friends, etc.)
      Note that having reviewers nominated by a journal editor is currently the rule in most journals. In that perspective, Peer community in will not be more exclusive than most journals. Actually, it will be even less exclusive since their will be no numerus clausus. In addition, the limited number of recommendations that a member of the community can write (1 or 2 per year, maximum 5) will give the way to a large diversity of scientific points of views and will reduce the risk that a few members are calling all the shots in the recommendations.
      Besides here are two key points that will guarantee that the community would remain open:
      – recommendations have to be conducted by at least two persons. Only one of these two persons will necessarily be member of the Peer Community in X. Hence, for each recommendation, one review might be written by a researcher who does not belong to the community.
      – even if members of the Peer Community in X are appointed by the Managing board, it is important to note that half the Managing board will be replaced each year. The composition of the Managing board will therefore change over time quite rapidly, further diminishing the risk of a drift toward an ‘exclusive club’.

      There will not be any “scientific” monitoring of the reviews written by the reviewers. However, the Managing board will perform a quality check on the format and the deontology of reviews and recommendations.
      The main reason why we did not opt for the system you describe (a system that is fine in principle) is to guarantee the lightest workload for everybody (Managing board, community). We feel that this is a key condition for the stability of the system. The initiative has to persist on a relatively long term in a context where most researchers cannot dedicate much energy to reviews/recommendations. If the initiative works, managing an uncontrolled influx of reviews could represent too large an amount of work and as such discourage members of the “monitoring board”. In addition, a certain proportion of the reviews would be rejected, leading to a waste of time and energy for the reviewers themselves.
      The second reason is that giving the Managing board the possibility to suppress/modify reviews and recommendations would largely increase the risk of an “exclusive club” effect.
      Importantly, reviews being published, there will be a possibility to leave comments on any recommended paper and on the reviews on which its recommendation is based. Commenting reviews will then be a powerful way to promote a diversity of views and perspectives.

  2. Hi Sergio
    Thanks for your positive comment. The creation of PCI Ecology is currently being discussed with colleagues. We keep in mind that you want to participate, and we’ll contact you directly.


  3. Well done. great initiative and was waiting for this style to come along. I am keen to participate if the subject area can include say Conservation Ecology, Socioecolgical systems, Resiience Science or Marine Ecology.


    1. Hi Stuart,
      Thanks for your nice words. As indicated to Sergio, the creation of PCI Ecology is currently being discussed with colleagues. PCI Ecology will certainly include conservation Ecology and Marine Ecology as thematic fields. We keep in mind that you are keen to participate, and we’ll contact you directly.
      Best regards


  4. Hi there, interesting initiative. Three questions:

    1. Most journals rely on copyright surrender from the authors. If the article was previously published under an open source licence this becomes impossible (or at least legally challenging). How do you expect this issue to be solved?

    2. Researchers and academics are today by and large evaluated by their output on ISI publications. Would you see a PCI X making it to the ISI database? Are you working towards such goal?

    3. I would like to kick start the PCI on GeoInformatics. How should I proceed?

    Thank you.


  5. Hi Luis.
    Thanks for your interest and questions.
    1. We do not publish articles, only peer-reviews and recommendations. So there is no copyright issue regarding the scientific papers.
    2. Researchers are more and more evaluated on the basis of their Google Scholar citation record. Preprints are referenced in Google Scholar. Thus the authors can track their citation number including those of their recommended preprints.
    3. Good idea. Contact Denis Bourguet, Benoit Facon and Thomas Guillemaud at contact[at] to explain/describe your project.


  6. Dear Thomas et al., with all due respect, your answer to question 1 makes me doubt you fully understand intellectual property laws. A document that is made available to the public on a website is automatically protected by copyright. If on top of that there is a so called “copy-left” licence, publication in a commercial journal, say Elsevier, Springer, becomes legally impossible. I exhort you to clarify this issue.

    In any event, I see the process you propose as a clear improvement over the closed peer review process we have today. Ideally, PCI would evolve to a completely replace traditional scientific journals.



  7. Hi
    We try to clarify this point:
    Typically, manuscripts for which a recommendation by a PCI (PCI Evol Biol) is requested are deposited in public repositories such as BiorXiv. BiorXiv allows the authors to “retain copyright and choose from several distribution/reuse options under which to make the article available (CC-BY, CC-BY-NC, CC-BY-ND, CC-BY-NC-ND, or no reuse)”. If authors want to submit their paper to a journal, they may ahve to transfer the copyright they own to the journal, depending on the publisher’s policy. This is a matter that concerns the authors and the publisher of the journal. From our side, as we do not publish preprints, we do not intervene in the copyright transfert.
    Some journals accept the existence of preprints on preprint servers, some accept with conditions, and some don’t (see, there is an entry in our FAQ about that). More and more accept preprints without conditions. Therefore authors must verify that their target journal accepts preprints in archives before submitting their paper to this journal, like anyone using preprints. This is not particularly specific to PCI Evol Biol.


  8. Recent events makes the following question crucial for me to decide whether I want to give PCI a try: what ensures that PCI cannot fall in the near or distant future into the hand of Elsevier, like Mendeley, SSRN and BePress did?


  9. Hi Benoît. The ‘raison d’être’ of Peer Community In is to be free for readers and authors and to be an alternative to publishing by private publishers. PCI is a non-profit, voluntary organisation, not a company. It is indicated in its status. On the contrary, Mendeley, SSRN and Bepress were companies from the begining. Best


  10. The Peer Community In concept is brilliant. This has the potential to encourage more pre-print submission and make the peer-review more transparent. It will also force publisher to become more friendly towards Open Access.

    I was not sure I saw a position on open access to code, materials, protocols, and data? Maybe that is implicit.



  11. Hi Nick
    thanks for the comment. This is what we try to do! About open access to data, protocol, etc. we indicate in the ‘ethical code of conduct’ page that: ‘Recommenders of PCI Evol Biol and reviewers must ensure that the data for recommended preprints are available to the readers, through deposition in an open data repository, such as Zenodo, Dryad or institutional repositories, for example. Deposited data must have a digital object identifier (DOI). They must also verify that details of the quantitative analyses (e.g. data treatment and statistical scripts in R, bioinformatic pipelines scripts, etc.) in the recommended preprints are available to the readers, as appendices or supplementary online materials (in this case, the supplementary material must have a digital object identifier (DOI)), for example.’

    There is nothing about material, and we might correct this in a close future.
    Thanks for the suggestion.
