What Are the Different Uses of Index Cards?

Index cards may seem plain and square, but they are anything but. Teachers may use them to share inspirational quotes with kids and their families. In the office, index cards can be employed to keep track of research, write quick notes for colleagues, make notes or to-do lists, manage projects, and organize just about anything. If you have a lot of cards, they can be neatly kept in a variety of index card holders and index card boxes.
