Although the foundation for admission of a business record usually is provided by the testimony of the custodian, the author, or some other witness familiar with the practices and procedures of the particular business, it is the business record itself, not the foundational affidavit, that serves as proof of the matter asserted. Without the introduction of the records themselves, a witness's testimony as to the contents of the records is inadmissible hearsay.
