Admissibility of business entries and photographic copies

(a) Any writing or record, whether in the form of an entry in a book or otherwise, made as a memorandum or record of any act, transaction, occurrence or event, shall be admissible as evidence of the act, transaction, occurrence or event, if the trial judge finds that it was made in the regular course of any business, and that it was the regular course of the business to make the writing or record at the time of the act, transaction, occurrence or event or within a reasonable time thereafter. (b) The writing or record shall not be rendered inadmissible by (1) a party's failure to produce as witnesses the person or persons who made the writing or record, or who have personal knowledge of the act, transaction, occurrence or event recorded or (2) the party's failure to show that such persons are unavailable as witnesses. Either of such facts and all other circumstances of the making of the writing or record, including lack of personal knowledge by the entrant or maker, may be shown to affect the weight of the evidence, but not to affect its admissibility. (c) Except as provided in the Freedom of Information Act, as defined in section 1-200, if any person in the regular course of business has kept or recorded any memorandum, writing, entry, print, representation or combination thereof, of any act, transaction, occurrence or event, and in the regular course of business has caused any or all of them to be recorded, copied or reproduced by any photographic, photostatic, microfilm, microcard, miniature photographic or other process which accurately reproduces or forms a durable medium for so reproducing the original, the original may be destroyed in the regular course of business unless its preservation is otherwise required by statute. The reproduction, when satisfactorily identified, shall be as admissible in evidence as the original in any judicial or administrative proceeding, whether the original is in existence or not, and an enlargement or facsimile of the reproduction shall be likewise admissible in evidence if the original reproduction is in existence and available for inspection under direction of court. The introduction of a reproduced record, enlargement or facsimile shall not preclude admission of the original. (d) The term “business” shall include business, profession, occupation and calling of every kind.
