You have to go online into your library account and put the books you want 'on hold.' You'll get the email notification when it's ready.
Curbside means you can request a book on your library card, and they'll email you when it comes in. When you go get it you give them your card number and they get your requests for you. I believe they have those, but best option is to search the catalog. Then you can ask them to hold whatever you want.
