Because each workbook can contain many sheets, you can organize various kinds of related information in a single file. As you see in the above figure, the Workbook is named Book1 (look at the Title bar). Book1 is the first thing you see when you start Excel XP. Book1 is an Excel-given name. If you do some work, you have to name it differently and save it if you want to be able to retrieve it in the future.
