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, is typical. Please note that in the case of abstract publication 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. Anyone (the author, his/her institution/company, the Engler-Bunte-Institut am Karlsruher Institut für Technologie, 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 abstract.

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

Crown copyright

This licence and copyright agreement 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 abstract. Authors are asked to use the following statement, which has been approved by the Information Policy department of The National Archives:

This work is distributed under the Creative Commons Attribution 4.0 License. This licence does not affect the Crown copyright work, which is re-usable under the Open Government Licence (OGL). The Creative Commons Attribution 4.0 License and the OGL are interoperable and do not conflict with, reduce or limit each other.
