The court reporter also keeps a copy of the documents provided to the deponent during the deposition for document identification questions, unless digital document and exhibit technology is employed, in which case the deponent and all parties receive the official exhibits in real time. The deponent normally has the right to read and sign the deposition transcript before it is filed with the court. The deponent cannot change his testimony as recorded by the court reporter in the deposition transcript, but under rule 30(e) the deponent can correct on an additional "errata sheet" any mistakes in the deposition transcript shortly after the transcript has been typed and bound.
