What are Index Cards?

An index card is a card made of cardstock ( large paper ) cut in a standard format, used in recording or storing discrete data. In the past they served as a card index for quick search of a library catalog. Carl Linnnaeus invented the system in 1760. Today they serve a primary purpose of storing information and are often used for learning as flashcards.

What are Index Cards Used For?

Index cards are used in many different applications and environments; in the home to keep and retrieve recipes and other organization records; within companies to keep presentations, project reports and store contact information, to do lists, quick notes, or used as flash cards. The uses are almost limitless, used by students, writers, project managers and so many more.

These note cards can store many types of information: summaries, paragraphs or quotations. Note cards are commonly used to record only the overall idea for large amounts of material.


There are many ways to use them including:

  1. As a quick and easy way to take notes.

  2. To store recipes, shopping lists, and other organizational information.

  3. For business, it can be used to record presentation notes, project research notes, and contact information.

  4. As a great way to brainstorm ideas.

  5. Used to help with studying for exams when used as flash cards.

  6. Used to track progress on projects, goals, and to-do lists

  7. As a way to rearrange or reorganize information quickly and easily.

  8. A great way to visually represent data or information.

  9. Perfect for carrying around small items of information or in your back pocket ready to capture your ideas or for recording quotes, or for use as visual aids.

  10. To capture title and citation information in academic research, with a first card used to create a card index to reference related entries.

  11. To create story-outlines, screenplays and novels

  12. Building a second brain

In the past, before the advent of digital ones, paper index cards were the often suggested organization method for researchers. A card index is a catalogue of subjects with references to the cards which provide fuller information about them. A card index provides the ability to search for various topics by subject, author, title, etc.


Plus, they can hold data, and won't run out of battery! They can easily fit into a back pocket - the sizes widely vary from standard size to larger cards. They are convenient methods for recording information or any other data.


When used to catalog organizational data, it is often common to create a card index using a first card. This helps to search the remaining cards. These days, especially with hyperlinked digital cards, the same job is done electronically. 


Index Cards are heavily used in academic research, not only for recording information but also for bibliographical citations.


This ability to be used in a virtually infinite number of ways, and for it to be so good at storing small amounts of information, make them so valuable. It's what makes them standard stationery in offices and schools.
