2307	 Dynamic Document Processing	 The current role of computers in automatic document processing is briefly outlined and some reasons are given why the early promise of library automation and of the mechanization of documentation processes has not been fulfilled. A new dynamic document environment is then outlined in which clustered files are searched and information is retrieved following an interactive user-controlled search process. Methods are described for an automatic query modification based on user needs and for a continuous reorganization of the stored information as a function of earlier file processing and of normal collection growth. The proposed procedures provide powerful tools for information retrieval and for the control of dynamic library collections in which new items are continually added and old ones are retired. automatic indexing automatic search and retrieval iterative searching mechanized library processing collection growth collection retirement feedback search
