Another iTunes Question

[Sambouka]

I have around 100 GB worth of music that I obviously can not fit all in 
my Powerbook. Hence, I have a portion of them on my External FW HD and 
the rest on my PB.

The only thing that bothers me is the dead tracks when I do not  have 
my FW HD connected. is there a way to have multiple libraries where I 
can see only the songs on my PB when the FW HD isn't connected?

Basically, I would like to have an option of two libraries:

To view and listen to all the songs on my PB.
To view and listen to all the songs on my PB and FW HD.

Thanks in advance.

Sam
