The use of external data bases to extend current awareness services based on internal resources at AWRE Aldermaston

This paper is an attempt to give the picture of a somewhat different approach from that at Harwell. Descriptions of the systems and the data bases being used at Aldermaston have already been recorded in some detail, especially by L. Corbett, and so will not be repeated here. I would on the other hand like to say something about the policy behind the decision to use external data bases, to include some more up‐to‐date assessments of the use being made of these services and their present costs, and finally some plans for future developments.
