Hereafter, in any county of the first class in this state where the collector of the revenue of the county is required by law to enforce the lien of the state for back taxes by suit against real estate charged with the lien, except in counties of the first class not having a charter form of government, the collector may employ some competent and reliable abstracter of his county to prepare memoranda of abstract to lands described in the tax bills to be furnished by the collector showing all conveyances, liens and charges against the real estate, as shown by the records of the county, which shall be duly certified to by the abstracter. The abstracts or memoranda when prepared and certified as herein specified shall be delivered to the tax attorney employed to bring the suits and he shall file them with the petition in the case, and they shall become the property of the purchaser at the tax sale.
