Shutting down a Mac

[Fionn]

Whenever I shut down my Mac it loses my Itunes library, my internet bookmarks and other stuff like that.

Do I use the sleep option?

How long have you had your computer? That shouldn't be happening...If it persists, you might consider Repairing Permissions: http://thesalon.blogspot.com/2009/04/if-you-use-mac-you-need-to-repair.html

If your account is a guest account that's what happens. Anything you might have saved is wiped when logging out. Might want to get your account changed to admin or standard.
