Or try KJots. I'm not sure if it's included in the default KDE, but it's here on Mandrake 9.2. You can categorize notes into "books." KNotes is very a simple, and I just use to write down my daily homework when I come home from school in columns numbered by my periods, and I just delete the entry when I've completed that assignment. Works well for me since I can keep it in the system tray and not on my task bar.
