I've used the passing-notes game in U.S. libraries, with decent results. It's tough because you can run into some pretty frigid specimens in academic libraries, especially at good schools. The key is to write something not lame and to make her feel like she's part of a secret or a little bit of slacker shenanigans.
This has worked for me:
1. Draw a hilarious, but quick-and-sloppy doodle of a third party (e.g., lame dude or girl sitting at a nearby table)
2. Draw an arrow so she can know exactly who you're talking about.
3. Write caption: "what do you think of my drawing?"
4. Wait for results. (e.g., "Your mean!" [misspelling intentional])
I once got a girl to laugh loudly in a quiet library. We exchanged a few more notes before I wrote, "let's take a 5-minute conversation break" and gestured to a nearby photocopy area. We talked and I warmed up the interaction more there.
