Tip: Changing between two iLife libraries (iTunes or iPhoto)

Many users desire multiple libraries for their iTunes and iPhoto applications.
While this is
possible by creating an entirely new account on the computer, this solution
isn't too practical.
In the latest versions of iTunes and iPhoto, Apple has built in the ability to
change or create
new libraries. In iTunes, for example, this is good if you want to keep a
library of personal
recordings or Garage Band compositions separate from your popular music.
Additionally, one
can maintain a separate library for either iTunes or iPhoto on an external disk.

To manage libraries in these two applications, open them and immediately press
and hold
the options key. This will bring up a small window with the options to either
create or choose
a new library. Hopefully Apple will provide a more direct library manager, but
for now
holding the options key at application startup is the way to manage libraries.
