Via Narratively: The Secret Life of a Public Library Security Guard
Very good read...maybe mostly because working at a public library, you work closely with these guys, and I'm grateful for that.
Image and quote from narratively
In a city of more than 66,000, there might be as many as 2,000 visitors every day. Indoor spaces that are actually open to the public are a rare find, and in a city like Portland, Maine — with months upon months of winter and an immense homeless population — the library becomes a living room of sorts. Keeping good guard of the library is delicate work. One must disrupt as few people as possible. Keeping the building safe and comfortable while at the same time truly public can be a precarious balance.
