What can you do yourself as a researcher?
Most publishers allow the post-print version of an article to be published as Open Access - "green Open Access".
At DTU, this is done by uploading the post-print version to the research database DTU Orbit. Researchers simply have to send their post-prints to DTU Library via firstname.lastname@example.org
Typically, publishers impose embargo-periods on post-prints. DTU Library makes sure that post-prints are made available in accordance with the copyright and embargo policies of the journal.
DTU Orbit gives you information on how the post-print must be cited.
The post-print version of a scientific article has been peer-reviewed and accepted for publication but still lacks a formal publisher layout. The intellectual content is identical to the version that will be published in the journal.
