- A thumb index (also known as a cut-in index) refers to the rounded notches or "thumb holes" cut into the fore-edge of pages in large reference books like dictionaries, encyclopedias, or Bibles.
- These allow quick navigation to specific sections (e.g., alphabet letters).
- The book itself is typically called a thumb-indexed edition, such as a thumb-indexed dictionary.
- For example, many editions of the Oxford English Dictionary or Merriam-Webster's Collegiate Dictionary feature this for easier use.
