I admit to photocopying some books back when I was in uni, but then those books are usually nowhere to be found in Malaysia (lecturer even asked us to photocopy it because it was too old an edition to try and find it here!)

But I try to get original books as much as possible now. Novels / storybooks especially. I agree with FidelisGVR that having a book nicely printed and pressed is truly satisfying. Most of the books I like to read don't have an ebook version anyways, so no hope in getting an ebook.
