Chen: Now can you show me how to find a book?
Lily: Well, the library's very big, and the books on food could be under cookery, or they could be in history, or even entertainment. So, the first thing to do is to look the book up in the online catalogue.
Chen: Where do I do that?
Lily: It's easy there are lots of computers in the library for that.
Chen: OK, I see.
Lily: Right, you look up the title first. When you've found the book, you'll see it has a class mark next to it. The class mark is one or two letters and a number Make a note of the class mark then look it up on the plan of the library. The plan shows you exactly what section of the library the books are actually kept in. |
