Publication journals and conferences sates some restrictions on publishing texts of papers accepted for publishing in their periodicals and proceedings, is it permeable to add such full texts in RG ?
Yes, the journals have the different publication policies. Some journals do not allow the author to share his/her work on other platform. It is better to check the journals policy before uploading the full text on open access or RG
This answer is a bit tangential to your question but it does explain why so many people put a preprint article on Researchgate. Obviously, this community is extremely helpful and some free proofreading is always helpful;-) But besides fixing the claiming rights to a new idea, it is interesting to know that Google Scholar has consistently considered Researchgate as a medium to highly ranked peer review journal. You and I know it is not, however when the GS algorithms analyze the corpus of documents "published " on Researchgate their comparison is very similar to anything on Springer et al. Many preprint and symposium papers on Researchgate are cited before real publication, significantly increasing the H index in some cases. Then there is the Google Scholar Profile itself. I realize that many people dismiss these profiles in preference for professional systems like Scorpus but GS is the only open source researcher ranking system. If not cancelled in the future, Google Scholar is a very useful for many reasons.
Normally an online-journal warrants free access to the authors for downloading. They have allowance to publice the text also afterwards in RG, publishing online the text in a journal. That's only my experience, there could exist althoug other regulations, I don't now. Another situation are prints press, here give publishers for instance the author of a contribution only after a longer period the allowance to publish. after the printed text is published, this changes also but in my own case E . I have to wait 18 months until I can upload the text for own use.
It depends on copyrights. If the journal is open accessed, it is legal to float a copy on researchGate. If someone has given a private copy for his/personal use only, he/she can't add that on researchGate. If he/she do so, will violation if copyright agreement and is illegal.
Several scientific publishers, including the American Chemical Society, are expanding their legal actions against sites that facilitate sharing of scientific articles in violation of copyright law.
The publishers are preparing to issue what could be millions of notices to the scientific networking site ResearchGate asking it to remove copyrighted material. ACS and Elsevier have also sued ResearchGate for copyright infringement.
Founded in 2008, ResearchGate is a for-profit company and now has more than 13 million members and 100 million publications, according to its website. Its funding comes from venture capital investment; investors include Bill Gates, Goldman Sachs Investment Partners, and Wellcome Trust. ResearchGate also sells advertisements that appear alongside its content.
But as many as 7 million articles that appear on ResearchGate do so in violation of copyright law, publishers allege.
“We have invested heavily in curation and publication processes to get validated, trusted material in a form that scientists can access,” says James Milne, ACS’s senior vice president for publishing, speaking on behalf of a group of publishers called the Coalition for Responsible Sharing. “We cannot allow ResearchGate to commercialize that material without contributing to the creation enterprise.” ResearchGate also alters articles for its business purposes and fails to update them when corrections or retractions are issued, the coalition says.
After two years of trying to work with ResearchGate, the International Association of Scientific Technical and Medical Publishers, of which ACS and Elsevier are members, issued a final proposal to the company on Sept. 16. The agreement would have allowed ResearchGate users to continue uploading documents as they do now. After material was uploaded, an automated system would check to see if the article was licensed to share publicly or privately.
ResearchGate declined the proposal. Publishers now have “no other choice” but to issue takedown notices and sue the company, the Coalition for Responsible Sharing says in a press release. ResearchGate is located in Germany, and the lawsuits were filed in Europe.
ACS, which publishes C&EN, estimates that more than 100,000 of its articles are hosted illegally by ResearchGate. ResearchGate did not respond to requests for comment.
ACS-copyrighted material also appears illegally on internet pirate site Sci-Hub, and ACS appears likely to succeed in a suit against the site, according to a preliminary finding released by a U.S. district court in Alexandria, Va.
Magistrate Judge John F. Anderson agreed with ACS that Sci-Hub violated ACS’s copyright and trademark protections when it provided free access to stolen journal articles. Anderson recommended that the court take several actions requested by ACS, including ordering internet service providers with a legal relationship with Sci-Hub, such as domain name registries or web hosting services that Sci-Hub pays, to cease facilitating access to Sci-Hub websites.
The filing is a recommendation to Judge Leonie M. Brinkema, who will issue a final ruling, likely within the next few months.
It varies from journal to journal. Please make sure of this when considering to upload full texts. Most journals I know (open access) allow this and most subscriber journals either completely disallows or may allow after a specified period, say a year or more after publication date.
I think that to be on the safe side, you should read carefully the copyright agreement of the publishers of your papers to see if they support self-archiving and other kinds of archiving. Mounting an article on RG could be considered as an exchange of information between researchers, and this is usually permitted in the copyright's clauses. To be sure, check the copyrights agreement.
As others mentioned the answer depends on the journal. An useful tool is the SHERPA/ROMEO website which provides information on copyright & self-archiving policies for most journals:
I share the same sentiments with other who have already responded that, its always safe to read the copyright agreement of the publishers of your papers to see if they support this, if not stated, contacting the journal before posting the article on these platforms may be wise to avoid treading on dangerous grounds.
