TM: Do you have a sense of where these books are coming from and who is putting them online?
[TRC:] I assume they are primarily produced by individuals like me – bibliophiles who want to share their favorite books with others. They likely own hundreds of books, and when asked what their favorite book is look at you like you are crazy before rattling of 10-15 authors, and then emailing you later with several more. The next time you see them, they have a bag of 5-10 books for you to borrow.
I’m sure that there are others – the compulsive collectors who download and re-share without ever reading one, the habitual pirates who want to be the first to upload a new release, and people with some other weird agenda that only they understand. [via]
