BSA Section 81 is now IEA Section 81A.

81.The Court shall presume the genuineness of every electronic or digital record purporting to be the Official Gazette, or purporting to be electronic or digital record directed by any law to be kept by any person, if such electronic or digital record is kept substantially in the form required by law and is produced from proper custody.

Explanation.—For the purposes of this section and section 93 electronic records are said to be in proper custody if they are in the place in which, and looked after by the person with whom such document is required to be kept; but no custody is improper if it is proved to have had a legitimate origin, or the circumstances of the particular case are such as to render that origin probable.
