We have all been at a public library enough to witness the inclination of the homeless to hang out there. It makes sense, doesn’t it? It’s open to the public, offers free shelter from the elements, provides entertainment, and has free facilities. The idea of using this public venue, which is funded by the community and for the community, to reach out to these individuals is relatively new and, to use a library term, overdue. In San Francisco, where more than 7,000 people are homeless, the city decided to place a social worker inside the main public library to do just that.
