Open access has become a choice for scientific publication. In many countries, open access publication has been made compulsory for publicly funded studies. Since 2013, government-funded research paper in United States must be made freely available within 12 months of publication. Such policy will ensure maximum accessibility and circulation of published articles. While the scientific community is benefited at large due to free access and distribution of published materials, open access publication is never free due to the various costs involved in the production, permanent archival and digitalisation of scholarly articles.
