The following policy does not concern Open Access publications, which are subject of their own policies, according to the Creative Commons licence CC BY.
In keeping with our efforts in support of the dissemination of research results, De Gruyter is pleased to announce its repository policy, under which the following conditions apply to authors of articles published in multi-authored works (journals, anthologies, edited volumes and databases):
AUTHOR WISHES TO INCLUDE HIS/HER ARTICLE ON A PERSONAL WEBSITE OR IN A REPOSITORY
De Gruyter allows authors the use of the final published version of an article (publisher pdf) for self-archiving (author's personal website) and/or archiving in an institutional repository (on a non-profit server) after an embargo period of 12 months after publication.
The published source must be acknowledged and a link to the journal home page or articles' DOI must be set.
Authors MAY NOT self-archive their articles in public and/or commercial subject based repositories.
Note for authors of NIH-funded research
De Gruyter acknowledges that the author of an US-agency-funded article retains the right to provide a copy of the final manuscript to agency upon acceptance for publication or thereafter, for public archiving in PubMed Central 12 months after publication. Please note that only the accepted authors’ version of the manuscript, not the PDF file of the published article, may be used for NIH archiving.
AUTHOR WISHES TO SEND ELECTRONIC OFFPRINTS (PDFS) TO COLLEAGUES
Authors may download offprint of the article as a PDF document. This document will explicitly be marked as the author's personal document.
Authors may send 30 copies of the article to colleagues. These articles will be marked as author copies as well.
