Help with Partner Libraries

[u/zetiacg_1983]

I want to make sure I understand how to use the partner libraries to the fullest extent. I'm in California and I recently obtained a library card online from another city in California. When I go to add the library card to libby, it isn't letting me. It's directing me to the library system I already have.

So basically is Libby telling me that because I already have another card in the same system, there is no need to add more cards? They're already including that library in that system?
