Dr. B recently blogged about nifty print-your own bookmarks. What I like best about them is the inclusion of a Note feature. I frequently just use small pieces of blank paper so I can jot down notes while I read (provided I don't own the book in which case I write all over the thing). For fiction, I sometimes need reminders of character names (especially when I've only got time to pick up the book twice a week and have forgotten everyone). For non fiction, well, I jot down things to blog or look up or just think about. I don't know if I'll use these things (the note space is a little cramped), but they sure are better looking than my usual scrap-paper bookmarks.
