• Does selling eBooks at a lower price than paper books encourage people to buy eBooks rather than paper books?
  • Are eBooks generally sold at lower prices than their paper counterparts?
    • Where this is not the case, are people prepared to pay more for the convenience of reading on their portable device(s)?

Some say (e.g.) that:

  • Reading n books on some electronic device surpasses the break-even point.

Libre lens:

  • People making a living directly or indirectly via the sale of (licenses to read/use) (in reality) non-rivalrous resources (such as digital copies of books, non-free software) made rivalrous artificially (e.g. via DRM) are having an impact on the environment: they consume food, use electricity, cars and otherwise pollute the environment, etc..
  • Is their collective impact being taken into account in the comparisons?
  • Is that impact significant as compared to alternative business models?
    • i.e. models alternative to some party/parties raking in money while they sleep as ‘consumers’ pay to download/access digital copies of restricted digital resources.
