Wheeling-Pittsburgh Steel Corporation (Appellant) received a citation for violating the Air Pollution Control Act, Act of January 8, 1960, P.L. (1959) 2119, as amended, 35 P.S. § 4001 et seq. because of visible emissions of greater than sixty percent opacity. Appellant was found guilty by a district justice of the peace and appealed to the Court of Common Pleas of Westmoreland County. The lower court dismissed the appeal. We affirm.
Appellant argues before this Court that (1) the lower court improperly limited Appellant's cross-examination

of the Commonwealth's witness and (2) that the court dismissed the appeal from a summary conviction, but failed to enter a judgment and impose sentence. Inasmuch as judgment of sentence has been entered in compliance with an order of this Court entered sua sponte the 29th day of January 1980, the latter issue is now moot.
With respect to the alleged error at trial, the record shows that the Appellant was allowed to bring to the attention of the Commonwealth's expert witness an article from a publication of the Natural Resource Section of the American Bar Association. When questioned about this article, the witness said he had not read it and was not familiar with the authors of the article. Thereupon, the court curtailed further questions on cross-examination, indicating to counsel for Appellant that he could properly use the material in argument or in Appellant's own case but, under the circumstances, not for cross-examination. Counsel for Appellant did not mention the article again.
Appellant never established that the article is authoritative in the field of Air Quality Control, nor that the witness should have read it.
An expert witness may be cross-examined on a work that he or she relied on in forming an opinion and on any work the witness recognizes as authoritative in the field. Brannon v. Lankenau Hospital, 254 Pa. Superior Ct. 352, 385 A.2d 1376 (1978); Evanuik v. University of Pittsburgh, 234 Pa. Superior Ct. 287, 338 A.2d 636 (1975). However, reference to the contents of a work is clearly improper where neither of the aforementioned tests is met and there is no other evidence that the work is authoritative in the field. See Evanuik, supra, at 291, 338 A.2d at 638.
Appellant's reliance on Cummings v. Nazareth Borough, 430 Pa. 255, 242 A.2d 460 (1968) on this issue is misplaced. In ...
