The school library, public or not?

As we said in class, it is important for a "public" sphere to have three attributes which are: access, invitation, and opportunity for involvement. I decided to spend a bit of time in the library, just looking at the way that things are set up and the different ways that it can be considered public and private. The library is accessible, it invites people with the appeal of knowledge and internet possibilities, and it allows people to participate in the many activities that are supported by the facility. It is private in the sense that it is only available to those who are students or staff on the campus; however, it is public in the sense that anyone who is a student or staff member on campus can use it. The way that the computers are set up gives a very private feel; the person next to you can not see what is on your monitor unless you give them permission to do so, or they have some excellently sly peeping skills. On the other hand, the tables and chairs that are set up (either for studying or just lounging and reading) in square groups of four chairs with a table in the center. This set up allows for the possibility of discussion and visiting, which gives the library a public feel. The types of writing in the library range from notes in personal books to status updates on facebook. The school library, is it public or not?
