1. 90% voracious reader 10% bibliophile. I don't care about the format (audio, ebook or print), I don't collect books, despite my huge TBR shelves, and I'll read anything (books, magazines, newspapers, Flipboard etc.).
2. Bibliophiles are more into, IMHO, the ownership of the books and bookish items than the average voracious reader. Both groups have a great love of books, but one seeks more permanence than the other.
