I recently created a profile on ResearchGate. And to add your publications list it requires you to upload the paper. Is it legal to upload published journal articles on public servers, where everyone can download it for free?

    it requires you to upload the paper — Actually, the software only requires you to upload a PDF file. If you're worried about legality of uploading a paper, you can always upload a substitute PDF file containing the sentence "This paper is available from the publisher at (url/DOI)."

    You don't even have to upload your papers. Or did they change anything in the past couple of days?

    Don't use researchgate at all. They are spammers & There are only students there, no experts. And everybody uses Google Scholar to search, so simply upload it on your personal home page / institutional repository if permitted by the license agreement. Commented Oct 3, 2016 at 16:58

    @Anony-Mousse in my field, plenty of senior scholars are on ResearchGate, and it's the first place many people look for things.

First of all, as far as I know, ResearchGate does not require uploading PDF files in order to add your research work to your profile in this website. However, it is very important to explore the possibility of uploading them, as it gives more visibility to your research and makes it available to more people. That is why I think your question is very interesting.

As @AnonymousMathematician and @gawdzilla already said, it all depends on the policy and agreements established by the publisher. You should ask the publisher. Period.

Now, I want to add some extra information about the alternatives we have to share our research without breaking any publishing agreement or rule.

Normally, there are several versions of a paper till it gets finally published:

a. The editor version: This is the final version of the paper, as it is published in the journal, with all the copyright stuff and so on. It is the final PDF, let us say, the one you normally keep as a record of your research.

b. The author version: This normally refers to an accepted version of the manuscript. It is the version that is finally qualified by the reviewers and accepted to publish by the editor. It is just your manuscript, just raw text (and tables and figures and so on), not usually formatted with the final journal style. Sometimes it is also called a postprint version.

c. A preprint version: It is also a sort of author version, but it usually refers to the submitted manuscript version before the reviewers do their job. It is the first (submitted) version of your manuscript.

So, in fact, I've listed them in a sort of reverse chronological order. :D

Now, if you want to make your research as visible and accessible as possible in ResearchGate (or other scientific social networks such as Academia.edu, etc.), which possibilities do you have? Let us see:

  1. You can upload the final (editor) version of your paper, as long as the publisher allows you to do that, but I do not think this happens very often. [Actually, there are some journals that follow an open-access policy, meaning that the authors keep the copyright of their work. But, anyway, you have to follow and stick to the final publishing agreement and see if you are allowed to distribute your paper by yourself, etc.]

If not, you do have other options:

  1. You can upload the author version. You should also check with the publisher if you are allowed to do so. Sometimes there is an embargo or vesting period and, after that period, you are allowed to publish or distribute the author version of your paper on your own.

  2. You can upload the preprint version. Publishers normally allow authors to publish or distribute preprints of their manuscripts, normally as technical reports. Anyway, you should ask the publisher, just in case.

  3. If none of the above options apply, then you always have the option of adding this text at the end of the 'abstract' field in the ResearchGate record for your paper:

    [ Full text available at http://... ]

Now, I want to add some practical examples from my own experience. Hope it helps.

In my case, I usually publish the preprint version of my papers as technical reports in the official repository of my university department. It is a quite common practice among some researchers in my field. Among other benefits, it prevents evil reviewers or editors to copy or plagiarise your research. Anyway, as I told you above, you should check with the publisher whether you are allowed to do so or not.

Now, this is an example of case (3): https://www.researchgate.net/publication/273349919_Optimal_Design_of_Pre-control_Plans, which contains a preprint version of this article that was already published as a technical report.

And here you have an example of case (4): https://www.researchgate.net/publication/45101373_Predicting_the_duration_of_chemotherapy-induced_neutropenia_new_scores_and_validation, which contains the abstract for this article I have coauthored. I will upload the author version in February 2017, when the 36-month embargo period finishes, according to the publisher rules. [Well, it is not actually an example of case (4), as you can see a full version of a preprint in this ResearchGate record. But the preprint is quite different from the final version in this case, so when I am allowed to upload the author version, it will replace the current preprint version.]

As a final remark, please, notice that it is not technically the same publish a research paper than just disseminate, distribute or propagate it. However, I have used them as synonyms in this answer, as sometimes it makes no real difference in the context of your question. [Actually, I think (I am not sure of this) that what you do in ResearchGate when you upload an author or a preprint version of a paper you have coauthored is not techincally publishing it...]

Hope it helps. Any comments to this answer will be welcomed. It is always good to learn new things... :)

    @nxkryptor This should be the correct answer. Commented Jul 14, 2016 at 9:36

Is it legal to upload published journal articles on public servers, where everyone can download it for free?

It depends on the publishing agreement you signed, which should specify which rights the authors and the publisher hold. The allocation of rights depends on the journal (and the field you are working in), and sometimes there are modifications or addenda for a specific paper.

You should keep copies of the publishing agreements for your papers, precisely so you can refer to them at times like this. If you don't have them, you can get an approximation by looking on the journal's website to see what their current policies are. The policies could have changed over time (and in principle the publisher could still enforce a stricter policy you agreed to in the past), but it's probably safe to post a paper online if the publisher allows it as part of the current publishing agreement. If you're feeling nervous, you could always ask the publisher whether you could follow the terms of the current publishing agreement for your paper that was published long ago.

    You can check on Sherpa/Romeo the standard policy of most publishers, even if it does not replace completely checking what you signed. Commented Aug 31, 2015 at 13:04

    Researchgate recently added a binding arbitration clause to their terms of service, taking effect 1 Dec 2017. I stronger encourage people to delete their accounts.

As mentioned in the other answers, it depends on your contract with your publisher.

http://www.howcanishareit.com/ indicates given a DOI whether a paper may be shared on ResearchGate or similar websites:

Also, as Benoît Kloeckner mentions in a comment, the RoMEO Journals database contains thousands of journals, labeled with their archiving policy (preprint/postprint/publisher's version):

enter image description here

Except of the database:

enter image description here

Of course, your contract is the reference, whereas those two resources are just approximations.

PS: ResearchGate has quite a bad reputation due to its spam/impersonation/etc. tendencies e.g. see Should I send a "cease-and-desist" letter to ResearchGate?


In most cases, is not legal at all. Normally you should only post the author version or post-print which is an accepted version of the manuscript. And always respect the embargo period (12-24 months...) Anyway, you should always check your Copyright Transfer Agreement. In many cases it's legal to post the author version in your institutional repository but not in ResearchGate


I've attended publishing talks from publishers. As advised by some above, it is necessary to check with the publisher for publishing guidelines.

Usually, you have to wait for the paper to be published. Then, if the publisher allows, you can upload your manuscript copy.

BUT do always check with the publisher in question to avoid violating any terms.


When you published your paper, you did transfer the copyright to the publisher. You did have to at least agree to, or even sign the "Copyright transfer form". It is a legal contract, and it governs your rights, depending on the publisher/journal policy.

Different publishers have different (default) policies regarding the rights, retained by the authors (I am talking here about Springer, Elsevier, IEEE, etc.) Some of them allow you the publication of your paper on your page, but not on specialized sites (like Researchgate), since those are their direct competition. Some of them allow you only the publication of final submitted manuscript, before publisher's editing was applied, on your web page, etc.

Please read the copyright policy of individual journal or even better, publisher. In case of conference papers, it depends on the publisher of the proceedings - if the organizers did publish the proceedings themselves without the external publishing house, ask them (but usually they will be fine with publication elsewhere).

So, to sum up:

1) Read what you signed when you submitted your paper to the journal/conference - the "Copyright transfer form" 2) if 1) is impractical or impossible, check the copyright policy of the journal/proceedings publisher. 3) As a last resort, ask the publisher.
