A process for microfilming and determination and storage of document film position information and evaluation of the data for reproduction of the document from the microfiche. The document specific identification or search data of a document to be filmed is fed into a computer memory, which outputs the memory address location opened in the form of a code to identify the document and reserves additional data storage space under the address. During filming of the document, the position data determined by a coordinate slide of the camera, controlled by a stepping motor on the microfiche, is reproducibly stored in the reserved memory location of the computer under the document specific data. The code associated with the document to be filmed is read by the camera or fed into it and passed to a camera memory. The filming data determined by the camera during filming of the document is correlated with the memory, which contains the identification and search data of the document under the address code. The procedure is carried out by a device for automatic microfilming of documents of different formats and for development of exposed microfiche in a continuous process with a computer controlled combination of certain systems.
