Most publishers own the rights to the articles in their journals. Anyone who wants to read the articles must pay to access them. Anyone who wants to use the articles in any way must obtain permission from the publisher and is often required to pay an additional fee.
Although many researchers can access the journals they need via their institution and think that their access is free, in reality it is not. The institution has often been involved in lengthy negotiations around the price of their site license and re-use of this content is limited.
Paying for access to content makes sense in the world of print publishing, where providing content to each new reader requires the production of an additional copy, but online it makes much less sense to charge for content when it is possible to provide access to all readers anywhere in the world.
Open Access (OA) stands for unrestricted access and unrestricted reuse. The author(s) and copyright holder(s) grant to all users a free, irrevocable, worldwide, perpetual right of access and a license to copy, use, distribute, transmit and display the work publicly and to make and distribute derivative works in any digital medium for any responsible purpose, subject to proper attribution of authorship, as well as the right to make small number of printed copies for their personal use. Open Access is a property of individual works.
Open Access should be seen as a means of accelerating scientific discovery by providing free and unrestricted access of scientific knowledge via the Internet. An essential role of Open Access is the long-term preservation of peer-reviewed scholarly journal articles and research data. Thus, Open Access initiative helps in unlocking the traditional methods of subscription articles and releasing information to tertiary level readers, who normally would not have access to first hand research studies. Realizing the potential of Open Access in terms of greater visibility within and beyond the scientific community, in recent years, there has been a tremendous boost to Open Access movement through various Open Access publishers.
