After your article has been accepted for publication, please inform the Editorial Office that you will choose open access publication. The Editorial Office will contact you and provide the DOI of your article as well as the OA license agreement for you to sign.
If you opt for Open Choice, you are not required to transfer copyright.
Open access articles which are ordered through the Open Choice program are clearly identified as open access – in the article PDF and HTML, in the article metadata, and in the article display at SpringerLink.
Please fill out and submit the OA order form at the website http://www.springer.com/manualopenchoiceorder.
After receiving the OA order form, Springer will invoice the open access publication charge.
