Difference between Section 159 and Section 160 of the Indian Evidence Act are given below:
Section 159 allows a witness, while under examination; refresh his memory by referring to any writing made by him at the time of the transaction concerning which he is questioned, or so soon afterwards that the Court considers it likely that the transaction was at that time fresh in the memory.
ADVERTISEMENTS:
Again with the permission of the Court the witness may refresh his memory by referring to a copy of such document.
The witness may even refer to any such writing made by any other person, but which was read by him at the time the transaction was fresh in his memory and when he read it, he knew it to be correct.

Section 160 provides for cases when the witness had no independent recollection say from lapse of memory of the transaction to which he wants to testify by looking at the document and states that although he has no such recollection he is sure that the contents of the document were correctly recorded at the time they were where a case of this character arises and the document itself has been tendered in evidence the document becomes primary evidence in the case.
