Federal Rules of Evidence – Rule 1006 (through March 1, 2020)
You can introduce a summary, chart, or calculation to prove the content of voluminous material if necessary for convenient examination and you make the voluminous material reasonably available for inspection and copying. The court may still make you produce the voluminous material.
The proponent may use a summary, chart, or calculation to prove the content of voluminous writings, recordings, or photographs that cannot be conveniently examined in court. The proponent must make the 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.
Selected Committee Notes
The admission of summaries of voluminous books, records, or documents offers the only practicable means of making their contents available to judge and jury. The rule recognizes this practice, with appropriate safeguards. 4 Wigmore §1230.
