What is Open Access?
Open Access is the international academic movement of publicly funded institutions making the results of their research available to anyone who is interested - without charging for it.
One of the most important advantages of open access is that it increases the visibility and use of academic research results. Worldwide, people without connections to a scholarly institution have access to results of scholarly research. Open Access improves the visibility of your scholarly output, which adds to your reputation as a researcher.
Research shows that Open Access publications are cited more often on the average than closed publications.
Green or gold?
Gold Open Access means that all publications in a journal are freely accessible to readers immediately and without restrictions. There are no subscriptions fees and publishers gain their income by charging authors (or their institutions) when articles are accepted. These charges are known as ‘article processing charges’ (APCs).
Green Open Access involves publishing in a traditional subscription journal as usual, but articles are also 'self-archived' in a repository. In some cases, an embargo period is set by the publisher. No charges are paid.
