Editor´s notice

The Computer Group has decided to publish in alternate months, beginning in July, the Computer Group News. This will contain a guide to current literature, and information about manuscripts available from the repository. In view of this increase in publication activity, the value of the Information Retrieval Catalog Cards in the back of each issue of these TRANSACTIONS, and the value of the Abstracts of Current Computer Literature are being reviewed. If you make use of either of these items, please write to me immediately. If there is little or no response from our readers, the cards and/or the abstracts will probably be discontinued.
