Most publishers offer a paid open access model via the payment of an article processing charge (APC). But, in most cases, authors can make their articles open access (and ensure compliance with the Tri-Agency Open Access Policy on Publications) without incurring any fees by following the Green Open Access (self-archiving) route.
The following captioned images will assist authors to understand the self-archiving process and differentiate between a post-print and a publisher PDF.
Read the captions at the bottom of this box for explanations of the images.
Authors should consult their copyright transfer agreement or Sherpa/RoMEO to find out what rights they have retained. Authors can search by publisher, but it is preferable to search by journal title in case individual titles have different permissions. Please see the Sherpa Romeo User Guide and the video tutorials for more detail.
For more detailed information, please review the following videos and consult the Sherpa Romeo User Guide.
