Abstract: Description of a technique for compressing data to be placed in computer auxiliary storage. The technique operates on the principle of taking two alphabetic characters frequently used in combination and replacing them with one unused special character code. Such one-for-two replacement has enabled the ILO to achieve a rate of compression of 43.5% on a data base of approximately 40,000 bibliographic records.
