How to mention a folder in a network?

http://askubuntu.com – I'm a returning user to Ubuntu, I've used it several years ago and now I'm getting back. I use calibre do manage my e-books collection, and I have a desktop running win7 and my notebook running Ubuntu. All my library is on my desktop, how can I make my Ubuntu's Calibre access my library on my desktop? Note: I can access my library normaly via file explorer. When I had windows on this notebook, I needed only to tell calibre that the way is: \\GUSTAVU-PC\bibliotecado I don't know what's the equivalent to this on Ubuntu, when I hovered the mouse over the mentioned folder on the file explore (HowTos)
