What kind of music are we talking about? Poppy genre, or classical...? O.o
Here's a few options anyway....
You can look at the books through this website (you don't have to buy anything) just check out the description and it'll have a list of theatrical/classical/or even poppy songs (usually when there's songbooks covering them, they're more likely to be played in a choir/band situation) : http://www.musicroom.com/browse/arrangement.aspx?category_id=store1_arrangementgroup7_arrangement69
Take a look at this list of non-classical soprano singers, if you have any favorites that you never knew were soprano, well that's awesome! : http://en.wikipedia.org/wiki/List_of_sopranos_in_non-classical_music
Also please know, that if you graduated school some time ago- it could be possible that your vocal range has changed. Probably lowered, or maybe it's even higher now, who knows! For females your voice continues changing throughout your life, most dramatically in your teens and 20s, and perhaps stabilizes a bit in your 30s. Just take a listen to Christina Aguilera's voice from when she started to now, her voice has gotten deeper, and lower, with a louder and rounder low-ends. So if you really want to know your vocal range and what not I suggest you visit a vocal teacher, or even your old choir instructor, and have them classify you.
