Re: How to get a girl that lives in the library.
Keep it simple. Don't over think it. If she's busy and it's in the day time you may want to consider direct. Many guys won't even do this because it takes balls. Showing her you have the balls to be direct about your intentions with her could definitely create attraction in just a few seconds. Most guys go under the radar during the day with "Where's X room" and "Do you have X book." She will likely catch onto this and just look at you as having little confidence. So I suggest to go direct.
"Hey this is random, but I have to say you intrigue me. In case you are in the mood for taking chances." Hand her your number and walk away. That's it.
