M: Yes, I’ve found a few useful books there, but the librarian at the main library suggested that the library here at the graduate school has more specialized materials.
W: Okay. It depends on what you want. We do subscribe to a large number of journals. Since you’re working on such a broad topic you’ll probably have to do a lot of digging.
M: Do you think I can get something relevant here?
W: It may take some time, but you’ll be able to find many articles relevant to your topic. We also have quite a few newspapers on microfilm.
M: I think I’ve come to the right place. How can I find out which journals you have?
W: There’s a list of all of them. But if you want to search by author or by subject you can use one of the computers over there. Everything we have is in there.
M: What if I run across a reference to a research study that isn’t available here?
W: You can request any outside materials just by typing your request into the computer.
M: You mean I can get materials from other universities?
W: Not only from other universities, but from virtually any public or private library in the United States. The only limitation is that outside materials cannot be checked out.
