A friend of mine let me borrow Dune 1-3. I loved them and felt I would definitely re-read Dune. When the deluxe box set of 1-3 came out I bought it but it is just sitting on my shelf. I do plan on rereading them but probably not for awhile. Sometimes I also just like having the books I’ve read on my shelf as “trophies”.
If I really, really like the book to the point where I’d like a physical copy to place on my shelf. I recently read through Doyle’s chronology of Sherlock Holmes stories on my tablet via Project Gutenburg and would love a complete collection in hard cover format. However, it seems most of the contemporary releases, judging by Amazon reviews, are riddled with typos, so I might have to pursue some obscure, out-of-print release instead.
If I like the book but only kind of, I might purchase a digital copy when it’s generously discounted, but I won’t go out of my way for it.
