Where did my Appleworks go after I reinstalled the software?!

Help! I am selling my iMac G5 and have erased my hard drive to clear my personal files, etc. and reinstalled my software...both Tiger and Leopard. However, I no longer appear to have Appleworks! Where did it go? I will need to have Appleworks for my buyer. I did backup my computer via an esternal drive. Any suggestions on How I can retrieve it? Thanks!
