The size or density of a document for memory storage and/or data transmission applications is significantly reduced through replacing words in the document with look-up locations in a vocabulary table. Two vocabulary tables are employed with each accommodating 128 different entry locations. Each of these entry locations may have a single word, a phrase, a word combination, or any data string including numerics. One of the tables would be a fixed table dedicated to universally used words stored in a ROS (read-only store), while the other table would be constructed in a RAM (random-access memory) with repetitively used words unique to a particular document to reflect a customized RAM file.
