Abstract
A Selective Dissemination of Information service based on computer scanning of Nuclear Science Abstracts tapes has operated at Harwell since October 1968. Users' interest profiles are constructed using Euratom index terms and NSA subject categories and matched against the Euratom index terms and subject categories assigned to each item in NSA.
