Rule 618. Impeachment of Expert by Learned Treatises

To the extent called to the attention of an expert witness upon cross-examination or relied upon by the witness in direct examination, statements contained in published treatises, periodicals, or pamphlets on a subject of history, medicine, or other science or art, established as a reliable authority by the testimony or admission of the witness, by other expert testimony, or by judicial notice, may be used to impeach the expert witness’s credibility but may not be received as substantive evidence.
