Abstract
Abstract A method of storing and retrieving information which has been gathered from a plurality of documents comprises the steps of (1) randomly filming a document on a roll of film while simultaneously imprinting a film index number on the document, (2) encoding the film index number, a library access number and a document number onto a storage means to form input data, (3) sorting the input data by means of electronic data processing equipment to place the input data in order by library access number and generate a magnetic tape containing the input data in order by library access number, (4) converting the ordered magnetic tape into a strip of film containing the input data in order by library access number and (5) cutting the ordered strip of film into a plurality of microfiche forms so that a library of microfiche forms arranged by library access number has been created.
