| RE: #s 1 & 2. It's their private property, and as such they may control it any way they want. You may take all the photographs you want from public property such as a public sidewalk though. You have the same control at your home and it's basically the same thing.
RE: #3. Again if the Carnegie Library is private property, they may control it any way they want. The design of some buildings, even some public ones, are under copyright. The NYSE is such a building, for example. You may photograph it, but you can't use the photo for commercial (even non-profit) without permission. Within any building, even government buildings, administrators can restrict many activities which they believe may be contrary to the atmosphere or purpose of the building. Try taking a photo inside a court house. These places (here in California) will even confiscate cellphones that have cameras. |
