The court may admit as evidence a summary, chart, or calculation offered to prove the content of voluminous admissible writings, recordings, or photographs that cannot be conveniently examined in court, whether or not they have been introduced into evidence.

The proponent must make the underlying originals or duplicates available for examination or copying, or both, by other parties at a reasonable time and place. And the court may order the proponent to produce them in court.

A summary, chart, or calculation that functions only as an illustrative aid is governed by Rule 107.
