(a) Documentary evidence may be received in the form of copies or excerpts where an original document is not readily available. On request, however, parties shall be given an opportunity to compare the copy with the original.
(b) Where a large number of similar documents is offered, the examiner may limit those admitted to a representative sample and may require the abstracting of relevant data from the documents and presentation of the abstracts in the form of an exhibit. The examiner shall allow all parties of record, or their representatives, an opportunity to examine the documents from which such abstracts are made.
