It will need one large room for the books and one for the employees to rest, have tea and eat their lunch in. It could be a place where people sit and relax and read some of the books if they want to.This is how I think the library should be designed to let people see the largest number of books. There should be shelves all round the room for people to keep books and some free-standing shelves in the middle of the room to hold even more. These shelves should be divided into sections so that each book shelf holds a certain kind of book. For example, all history books should be organized by date so that people can easily find books they want.My idea will help improve the education of students in our community. It will also give the adults an interest and keep their minds active.I hope you will support my idea.Step 7 Homework1. Finish off the Workbook exercises.2.
