If i promote these authors and priceless texts, writings and pieces in my blog, it further enhances the popularity of those impacted / or authors quoted herein.
Again, in this era almost everybody passes on copies of what they own and if i have purchased the copy, i am then reserved the right to read and share it as i want. Why would anyone pay for some thing which many others; hundreds if not thousands own electronically either legally or purchased? Under what grounds should it be regarded as legal or illegal when the origin could have been acquired legally?
When and if one publication has already been published there is no control as to how many of these copies are circulated for anyone could easy duplicate them. Royalty paid to the author is also a once off basis and repeated only when recirculation and a revised edition is made..
