Can I have two separate photo libraries on a Mac
is it possible to have two separate photo libraries one on an external disc and one on the internal SSD - use both independently but not corrupt or merge them?

Yes, if the external drive contains a volume formatted as Mac OS Extended. Launch iPhoto, Aperture, or Photos with the Option key held down to switch between them or create a new one.
