As far as research goes Kirn library has a collection of local historical documents unrivaled in the region. That is something no library in the Beach, or any other community in Hampton Roads can provide.
I think that a partnership with TCC would have it's advantages (Like TCC seems to have money that they want to spend on a library) but there will be logistical problems. Will students have more priviledge and access than the common citizen.
Downtown Norfolk is the cultural, business and entertainment center of Hampton Roads. Adding a downtown library to rival the Va Beach Central library with the addition of the aforementioned historical documents will only increse downtown's attractiveness and viability.
The city needs to realize this and dig into their own pockets.
