Open Access Resources

What is Open Access?

Open Access (OA) is defined by SPARC (Scholarly Publishing and Academic Resources Coalition) as “Free, immediate, online availability of research articles coupled with the rights to use these articles fully in the digital environment. Open Access ensures that anyone can access and use these results—to turn ideas into industries and breakthroughs into better lives.”

Green Open Access

In the scholarly publishing environment, there are 3 types of open access. They are:

  • Green OA (self-archiving)
    • Authors are granted archival right for articles published in subscription journals.
    • CDC Stacks is the institutional repository of record for CDC authors.
  • Gold OA
  • Hybrid OA
    • Many subscription journals provide authors with a choice to publish their articles as Open Access. Article processing charges will typically be incurred by the author if that model is requested.
    • Many authors choose this model to increase availability of their research.
