A list type data storing and retrieving system includes an analyzing circuit for analyzing a structure of list type data and outputting symbols constituting the data and appearance position data of each symbol in each list type data, a storage circuit for storing the position data output from the analyzing circuit, symbols respectively assigned to the position data, and at least one identifier set for the symbols assigned to the position data to specify the input list type data, and a retrieval circuit for reading out sets of identifiers including the same symbols and position data as symbols constituting list type data to be input and retrieved and corresponding position data or identifiers including variable symbols in position data having a higher order than that of the position data from the storage means with respect to all symbols constituting the input list type data, and outputting list type data specified by identifiers common to all the symbols as unifiable candidates.
