The advantage of walking freely is to stroll around at will and look at whatever interests you encounter. The building in front of you looks magnificent. When you come closer to the New South Wales State Library, you can have a free one-hour lecture. Considering that English is too sloppy, you'd better take a look at it and feel it for yourself. There are quite a lot of people who study by themselves. The three top walls of books feel very comfortable, especially the top of which is made of glass windows. In such fine weather as today, there is no need to turn on the light at all.
