Bookmark. I feel as if I'm hurting the book if I fold it. I've had the same bookmark for a long time...and if I don't have it with me, I'd use a leaf.
I try stopping a the end of chapters and then it is usually not a big deal.
I read mostly pocketbooks, they have a tendency to want to open on the page you last closed the book.
I try to remember the page regardless.
I use a piece of paper (bookmark). I'd never dog-ear my books! Because I don't want to hurt the poor book *hugs book*
Bookmark, definitely. I buy most of my books at this book store which gives you a bookmark each time you buy a book there, just simple cardboard ones, so I'm never in short supply.
I can understand what Caroline states in the OP but I see general wear and tear from reading and carrying it around as signs of affection for said book.
i can get a little lazy and won't want to get up and find a bookmark...
and it depends on what condition its in: if new, bookmark, if not, dog ear
I try to use bookmarks when I first get a book, but I always end up dog-earing the pages.
It is the way. I don't actually have any bookmarks xD I just use paper.
I generally dog-ear, penmark, scratch out...basically destroy my books. It comes from years of taking notes on them (I majored in English) and then losing my notes :(
I feel guilty about it, but dog ears. I buy new bookmarks or make my own, swear to myself that I'll use them from now on and they still never seem to be within reach when I'm reading. Sigh.
For me, how I mark the page depends on what condition it was when I got it. When it comes to old paper backs, most of the ones I have already have dog-eared pages, so I just go ahead and do it. When I get new paper back books, I tend to use sticky notes. For hard back books I normally just use the flap. For the first chunk of book I use the front flap, for the second, the back one. I sometimes use slips of paper, but I always lose them or they fall out.
I try to keep a bookmark handy so as not to ruin my books (often they are library books, and you aren't supposed to dog-ear them), but if I'm in a hurry, and it's my copy, I will dog-ear it. If it's an older book, I wouldn't dream of it, no matter what, but a new copy, why not?
Most of my books tend to be either library books or borrowed from other people, so I've just gotten into the habit of using bookmarks. Not fancy ones, though, just scraps of paper or notecards.
