Copyright Transfers

Many authors have strict regulations in their contract of employment regarding their works. A transfer of copyright to the institution or company is usual as well as the reservation of specific usage rights. Please note that in case of Open Access publications in combination with a Creative Commons License a transfer of the copyright to the institution is possible as it belongs to the author anyway and is not subject to the publisher.

Any usage rights are regulated through the Creative Commons License. As Copernicus Publications is using 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 a statement "all rights reserved" in any published paper.

A copyright transfer from the author to his/her institution/company will be expressed in a special "Copyright Statement" at the end of the publication rather than on the first page in the article citation header. Authors are asked to include the following sentence: "The author's copyright for this publication is transferred to institution/company".

Crown Copyright

The license and copyright agreement of Copernicus Publications respects the Crown Copyright. For works written by authors affiliated to the British Government and its institutions a copyright statement will be included at the end of the publication. Authors are asked to use the following sentence: "This work is distributed under the Creative Commons Attribution 3.0 License together with an author copyright. This license does not conflict with the regulations of the Crown Copyright."

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 allow/confirm a reproduction. We would suggest to contact the author to inform him/her about the further usage of the material. But as the author decided to publish the scientific results under the "CC-BY" license, he/she decided to share the work under the condition that the original authors must be given credit.
