Under Rule of Evidence 803(18) hearsay exception, an expert may be cross-examined concerning learned treatises (periodicals, pamphlets and treatises) if:
a. it is called to the attention of the witness on cross or it was relied on by the witness on direct, and
b. it is reliable authority established by:
(1) admission on cross;
(2) judicial notice, or
(3) testimony by another expert.
Substantive Evidence: Although the treatise itself is inadmissible, it may be read to the trier of fact and is substantive evidence (not just admissible to impeach the expert).
