Copyright transfers 

Many authors have strict regulations in their employment contract regarding their publications. A transfer of copyright to the institution or company is common as well as the reservation of specific usage rights. In open-access publications in combination with the Creative Commons License, a transfer of the copyright to the institution is possible as it belongs to the author anyway.

Any usage rights are regulated through the Creative Commons License. As Copernicus Publications uses the Creative Commons Attribution 3.0 License, anyone (the author, his/her institution/company, the publisher, as well as the public) is free to copy, distribute, transmit, and adapt the work as long as the original author is given credit (see above). Therefore, specific usage rights cannot be reserved by the author or his/her institution/company, and the publisher cannot include the statement "all rights reserved" in any published paper.

A copyright transfer from the author to his/her institution/company can be expressed in a special "copyright statement" at the end of the publication. Authors are asked to include the following sentence: "The author's copyright for this publication has been transferred to institution/company".

Crown copyright 

The licence and copyright agreement of Copernicus Publications respects the Crown copyright. For articles written by authors affiliated with the British Government and its institutions, a copyright statement will be included as indicated in the manuscript preparation guidelines. Authors are asked to use the following statement, which has been approved by the Information Policy department of The National Archives:

The works published in this journal are distributed under the Creative Commons Attribution 3.0 License. This licence does not affect the Crown copyright work, which is re-usable under the Open Government Licence (OGL). The Creative Commons Attribution 3.0 License and the OGL are interoperable and do not conflict with, reduce or limit each other.

Reproduction request 

All articles published by Copernicus Publications are licensed under the Creative Commons Attribution 3.0 License (see details above) together with an author copyright. Therefore, there is no need from the publisher's side to give permission for the reproduction of articles. We suggest contacting the author to inform him/her about the further usage of the material. However, as the author decided to publish the scientific results under the CC-BY licence, he/she consented to share the work under the condition that the original authors be given credit.
