Alas, indi booksellers are tomorrows Blockbuster. Probably 90% of what I read is not digital. Paper professional journal articles are an annoyance to file and retrieve, so I read PDFs. I am reading 3 books at the moment - 2 pdfs and 1 hardbound. I just published a paper academic book which is also downloadable. Alas, though I do not make a nickel, the book sells for $63! That is a rip, but I am sure many readers will find cheaper access.
