ABSTRACT:
A system of preserving the integrity of research and comparable data regularly entered into an electronically accessible memory by printing it out periodically upon a form of protected document stock which reveals the fact of copying in every xerographic copy of an original sheet of such stock, and which is accounted for, sheet by sheet, through the use of a unique serial number assigned by the manufacturer of the stock and recorded by him as issued to a given customer/user, and by the use of a record of distribution maintained by the records custodian of a given customer/user to identify specific serially-numbered sheets of such stock as having been issued to a particular person on a particular date, and who collects or receives the printed out stock as a permanent record of the information recorded.
