To facilitate readers across the globe, Progressive Academic Publishing adopts the policy of providing free and open access to full text papers. We do not charge any subscription fees from the readers. Adopting the alternative model, we charge publication fee from authors to partially cover article handling charges. After the paper is accepted, author will be asked to pay Article Processing Fee. Processing fee for an accepted paper up to 5000 words is US$ 90. Each page in addition to 5000 words will be charged @ US$ 5.
