In 1966 the Research and Development department of National Cash Register (NCR) of Dayton, Ohio produced an edition of all 1245 pages of the World Publishing Company's No. 715 Bible on a single 2" x 1-3/4" photochromatic microform (PCMI) The microform contained both the Old Testament on 773 pages and the New Testament on 746 pages, and was issued in a paper sleeve with title on the cover and information about the process inside and on the back.
On the microform each page of double column Bible text was about 0.5 mm wide and 1 mm high. Each text character was 8 um high (ie 8/1000ths of a millimeter). NCR noted on the paper wallet provided with the microform that this represented a linear reduction of about 250:1 or an area reduction of 62,500:1. This would correspond to the original text being circa 2 mm high. To put this into perspective, NCR also noted that if this reduction was used on the millions of books on the 270+ miles of shelving in the Library of Congress, the entire Library of Congress as it existed in 1966 could be stored in six standard filing cabinets.
♦ In 1971 Apollo 14 lunar module pilot Edgar D. Mitchell carried 100 of the microform bibles aboard the lunar module Antares, as confirmed by NASA's official manifest. Launched January 31, 1971, Mitchell and the bibles reached the Fra Mauro formation of the Moon on February 5 aboard the Antares before returning to the command module for the voyage back to Earth. This was the first edition of the Bible to reach the Moon, and probably the first book of any kind of reach the moon and return. A second parcel containing 200 microform Bibles flew in Edgar Mitchell's command module "PPK" bag in lunar orbit, and did not land. These 200 copies represented extra Bibles to be used if something happened to the lunar module copies.
