Video narration
Picture the timetable you check at school: rows name lessons; columns show information. Now bring that idea to the library. The librarian has a list in Microsoft Word: "Stories of the Prophets," ten copies, and "Algerian History," five. New books have arrived. To add each book, the student adds a row. One row holds one book's entry, so every title stays in its own place. Then the librarian wants each author and publication year recorded. The student adds two columns, one for each new kind of information. Finally, some listed books are no longer in the library. First, select the rows for those books-that means mark each complete entry. Then delete those rows from the table, not the books themselves. And the list is ready: rows for new books, columns for their details, and missing titles removed. Clear and current.
