The contents of voluminous writings, recordings, or photographs which cannot conveniently be examined in court may be presented in the form of a chart, summary, or calculation. The originals, or duplicates, shall be made available for examination or copying, or both, by other parties at a reasonable time and place. The court may order that they be produced in court.

Committee Comment-1977
In cases involving voluminous records, the only practical way to introduce the evidence in a meaningful fashion is by resorting to charts, summaries, or calculations. The rule does not require that the original documents be introduced into evidence. However, they must be made available for inspection or copying. The court has the power to require production of the original documents in court.
