An entry in an account kept in a book or by a card system or by any other system of keeping accounts is not inadmissible in any civil proceeding as evidence of the facts stated in the entry because it is transcribed or because it is hearsay or self-serving if the court finds that the entry was made in good faith in the regular course of business and before the beginning of the civil proceeding. The court in its discretion, before admitting the entry in evidence, may, to such extent as it considers practicable or desirable but to no greater extent than the law required before June 30, 1933, require the party offering the evidence to produce and offer in evidence the original entry, writing, document or account from which the entry offered or the facts stated in the entry were transcribed or taken and to call as the party's witness any person who made the entry offered or the original or any other entry, writing, document or account from which the entry offered or the facts stated in the entry were transcribed or taken or who has personal knowledge of the facts stated in the entry offered.   [RR 2025, c. 2, Pt. D, §9 (COR).]
