then transmitted to the Document Room of the Office of United States Chief of Counsel, with a covering sheet prepared by the screeners showing the title or nature of the document, the personalities involved, and its importance. In the Document Room, a trial identification number was given to each document and to each group of documents, in cases where it was desirable for the sake of clarity to file several documents together.

"6. United States documents were given trial identification numbers in one of five series designated by the letters: "PS", "L", "R", "C", and "EC", indicating the means of acquisition of the documents. Within each series documents were listed numerically.

If the officers preparing the certified translation; or one of the of officers working on the briefs, found it necessary to examine the original document, this was done within the Document Room in the section set aside for that purpose. The only exception to this strict rule has been where it has been occasionally necessary to present the original document to Defense Counsel for examination.
