If I have borrowed a book, I always use whatever I have at hand as a bookmark – usually a business card or a receipt – and I try to be as careful as possible with the pages and covers.
If it is my own book, however, I do dog-ear. I am not sure why because I always donate my books and I know other people don’t like it, but I like my favourite books to have battered spines and dogears – it shows that they are loved and used and appreciated.
What do you do?
