A system for using market-available scanner and character recognition hardware and software in preparing information from documents for mass storage. Results of character recognition are selectively defined in image and extracted from storage. A camera can also be used for digitizing large and small documents as well as microfilm and microfiche. A multitasking controller with its own microprocessor and RAM provides real time processing. The contents of documents can be stored in image, totally or selectively, conversion from digitized image can be made totally and selectively and passwords from documents can be identified and stored in code. Keyed information can be added as each document's contents are prepared.
