Bouvier's Law Dictionary, Revised 6th Ed (1856):

COPY. A copy is a true transcript of an original writing.
     2. Copies cannot be given in evidence, unless proof is made that the
originals, from which they are taken, are lost, or in the power of the
opposite party; and in the latter case, that notice has been given him to
produce the original. See 12 Vin. Abr. 97; Phil. Ev. Index, h.t.; Poth.
Obl. Pt. 4, c. 1, art. 33 Bouv. Inst. n. 3055. 3. To prove a copy of a
record, the witness must be able to swear that he has examined it, line for
line, with the original, or has examined the copy, while another person read
the original. 1 Campb. R. 469. It is not requisite that the persons
examining should exchange, papers, and read them alternately. 2 Taunt. R.
470. Vide, generally, 3 Bouv. Inst. n. 3106-10; 1 Stark. R. 183; 2 E. C. L.
Rep. 183; 4 Campb. 372; 2 Burr.1179; B.N.P.129; 1 Carr. & P. 578. An
examined copy of the books of unincorporated banks are not, per se,
evidence. 12 S. & R. 256. See 13 S. & R. 135, 334; 2 N. & McC. 299.
