If you see any other libraries, congrats! You should be able to log into them using your home library card but in most cases their books won’t show up in your home library catalog. To make things easier, you have to add them as a new library to your Libby app. Once you do that, you can search a title on Libby and if it’s available you’ll get the checkout/place hold button. When you tap it, it’ll show you which libraries have it and give you the option of where you want to borrow from! Enjoy!
