Only Display Catalog to Patrons?

Hi,

I am creating a personal library to track my books and other media and to allow my friends to see what I have that they want to borrow. From what I can see in TinyCat my catalog is open for display to whomever finds the site. I would like to limit display to those who login via their patron account.

Is there a way to do this? From what I can find in the settings it appears that a catalog is either available to everyone (public) or to no one (private.)

Thanks for your help!

Never mind, after more research, I came to accept that it is all or nothing. :)
