Electronic and reproduced documents admissibility recognized, allowing microfilms, facsimiles and computer printouts to be used without originals. Microfilms, facsimile copies, computer-produced printed materials and electronically stored information (including hard copies) are deemed documents and admissible without the original as evidence of their contents. A certificate identifying the document, describing its production and giving particulars of any device used, is itself evidence of the matters certified and may state facts to the best of the certifier's knowledge and belief.
