I had first come across this technology when I had published, The Road to pSingularity, and had explained this new publishing paradigm in a post in 2007. The trouble then was that these print-on-demand publishers were based in the US and the price of the book was comparable to a US retail price which is quite high for us in India. Moreover the shipping cost was very often more than the cost of the book. Thus the whole process was not quite economically viable.
However the arrival of of print-on-demand vendors in India have altered the economics dramatically. Recently, I had the pleasure of publishing the first volume of the VGSOM Management Monograph Series through Pothi and the results were very satisfying.
A perfectly bound paperback copy of my 154 page book Information Systems for Crime Management is now available at Rs 235 only from Pothi and since the books is being shipped from Bangalore, the cost is quite affordable -- and comparable to any other online bookstore in India.
Authors writing on niche topics may use this technology to publish their works.
