The rather drastic changes in the Cataloguing Rules of University College London, which were described in Vol. 12, no. 2 of this journal, published in June 1956, soon became accepted routine to the inconvenience of no one, so far as is known, except of the cataloguers whose task it was to make the necessary adjustments and to recatalogue small batches of cards from time to time. This inconvenience was more than compensated by the comparative simplicity of headings for both main and subsidiary entries, and by a reduction in the number of added entries needed.
