Nice job! In my town, too, the library is open only 4 hours on Sunday. There is also a loud buzzing light bulb on the first floor that drives me crazy. I really like your idea of attending to the library as a resource that benefits many people. You can find other things to improve about the library, too. Also, since this is an admissions essay, you can impress them by adding a few sentences that give details about your intellectual experiences at the library that have made it so important to you. The library is a place full of memories for many people.
Finally, most importantly, continue with your theme of the library being a social equalizer that brings people together and evens the odds.
And what else can be improved about it... the resources? The computers? Also, does this tie in with your intended major or career in any way? (I don't necessarily mean the library, but rather, the idea of social equity or public works?)
