What is your preferred method of marking pages within a book

[Glorb]

I picked Other, which secretly means "all of the above". I don't normally own bookmarks, so I try to mark my books with random objects, although I usually just dog-ear my cheaper newsprint books (like Tom Clancy paperbacks, airport novels and such).

Either remember the pages or use a bookmark. I use a bookmark more often, though.

[Kuromatsu]

Since I major in comic book reading, remembering the page number is the easiest method.

[Mr. Melee]

I shudder at the thought of bending page corners to mark a place in a book; or for any reason really.

Seconded. Dog-earing seems rather unintelligent when a bookmark could serve the same purpose better.

For some reason, I always lose bookmarks. So, I just remember my page.

[N64 Chick]

I usually try to stop reading between chapters so I only have to remember what chapter I left off on. Otherwise, I suppose any ol' piece of paper will do the trick.
