Welcome to the Apple Discussions.
You don't have to create a new Library, you can simply keep that Library on the external and use it from there.
To create a new Library: Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
Managing Multiple Libraries - including moving pics/albums/rolls and metadata between them - is greatly facilitated by using iPhoto Library Manager
To trash a Library: drag the entire iPhoto Library from your Pictures Folder to the trash and empty the trash.
