Either return it now if that takes you less than 2 min to do that or defer it. I would probably put it as a next action in an @errands context or set a reminder for a day that I'm near the library. ;)

Call, IM or email the library and renew it, or do it online. (312) 747-4636

I can't renew it once it is late, but I can bring it by the dropbox tonight. I will pay up this weekend and sin no more. ^_^

Thanks for the help!
