Edit: I just checked the calibre website. Look at the “Library” menu at the top it will allow you to do this:
“Switch/create library…: Allows you to; a) connect to a pre-existing calibre library at another location, b) create an empty library at a new location or, c) move the current library to a newly specified location”[/QUOTE]

Thank you, drofgnal. And you are right. That was exactly what I needed to do. Everything is working exactly as it should now.
I was sure it would be something simple but I couldn't get my mind wrapped around it to see it last night.
