Can you please erase the doubt from my mind regarding 'Pay and Publish' versus 'Free Publication,' because in both the cases money is being demanded either from the author or the reader.
In the publishing industry under 'Pay and Publish' the author/s need to pay the publication charges and in case of 'Free Publication' the reader/s need to pay some amount in the form of so-called 'ACCESS.' Then, where is the ethics of research and how can we claim the authenticity of the so-called reputed publishers who are free for contributors but are earning huge profits from the individuals or institutions. Please through some light on this.
