I have two 2005 Cisco books. One says 'Intro' and one 'ICND'. Is this enough to prepare for the CCNA?

These are Cisco Press books. They were packaged together. I just want to know if they will prepare me for the current CCNA or are they too old. I also see a lot of ICND 1 and 2, but mine just say 'Intro' and 'ICND'?
