Relevant portions of books, papers, or documents, shall be plainly designated and distinguished from all irrelevant portions before the relevant material may be offered into evidence. Where the irrelevant material in the book, paper, or document is voluminous so as to encumber the record, the book, paper or document may be marked for identification and the relevant material read into the record. Upon direction of the presiding Board member, a true copy of the relevant matter may be received as an exhibit, provided that copies are delivered to all parties of record and provided all parties of record are afforded an opportunity to examine the book, paper, or document, and to offer in evidence in like manner other portions thereof, if found to be material and relevant.
