25 Pa. Stat. § 2606
Whenever under the provisions of this act notice is required to be given by newspaper publication in any county or in any municipal subdivision thereof, such notice shall be published in at least two and not more than three newspapers of general circulation as defined in the "Newspaper Advertising Act," approved May 16, 1929 (Pamphlet Laws 1784). At least one of said newspapers shall represent the majority party, and at least one shall represent the minority party, if there be that many published within the limits of such county or municipal subdivision. If there are not two such newspapers, then publication shall be made in at least either one newspaper of general circulation representing the majority party or at least one newspaper of general circulation representing the minority party, whichever is published in such county, and at least one newspaper of general circulation representing the other party published in an adjacent county and circulating in such county or municipal subdivision in which such notice is required to be published: Provided, however, That if in any such county, or in any municipal subdivision thereof, there are at least three newspapers of general circulation published within the limits of such county or municipal subdivision, the foregoing provisions of this section shall be deemed complied with if publication shall be made in all of the said newspapers in the county or municipal subdivision, notwithstanding that all such newspapers may represent either the majority party or the minority party. Whenever such notice relates to any matter or proceeding in court or to the sale of bonds or increase of indebtedness, the same shall also be published in the legal newspaper, if any in the proper county, provided publication can be made therein on the same day or days as publication is made in newspapers of general circulation.
