Nice and direct!
I would just advice you to watch out for one thing:
Fast number closes like this that involves no kino or escalation but just talk can sometimes lead to issues when it comes to setting up day 2.
Yor tactics were good though, you should be proud.
However; I have done a lot of these really fast number closes, sometimes within seconds the problem then is that you catch the girl off guard so when you call her, she will have had time to think of a reason not to see you.
I have two ways of dealing with this:
1. Find something mutual, in this case you had the mythology books, tell her about some great thing you guys could do together that relates to that, and then take her number, this way you will already have the first "date" set up nd she will even be excited about it!
2. Call her, introduce yourself and before she says anything, before she has time to reject you (not saying she will but don't give her the chance) throw in a disqualifier, something that makes her think all you want is friendship, this will make her feel more comfortable and when you see each other for day 2 you can start playing the game again and build the attraction, the important thing is that you get day 2.
Now there is a third option, a little more bold, and sometimes more efficient. I'm not an expert on this one but I know it works.
Don't call her, text her, and start playing a cocky/naughty sexual text game with her, drive her crazy until she suggests the date, this takes practice but is useful because when you see her on day 2 your work will already be done before hand!
