Open Access means making research results freely and available on the internet, to anyone who wants to read, quote or download the articles. Some of the benefits by publishing Open Access are that the visibility of the publications increases, and gives greater impact factor and more citations. There are different models for publishing Open Access:
- Gold: Means that the article is openly available on the internet, but article processing charges, APC, may occur.
- Green: Means that the article is published in a traditional subscription-based journal that allows the author to register a full-text copy of the article in a publication database. This is also known as parallel publishing.
- Hybrid: Is a variant of Gold Open Access and means that the article is published in a traditional subscription-based journal that also requires article processing charges, APC, for publishing the scientific article freely available on the internet, while other articles in the journal still require subscription for access.
