6. CLASSIFICATION OF PUBLICATIONS ACCORDING TO TOPIC
The publications are listed under each topic in the following order: reports, papers, patents, other technical publications. Because the topics are very closely allied, many publications could have been listed under more than one topic. A reader in search of publications on a particular subject is therefore advised to consult all the topics relevant to his subject. Copies of most of the reports and other technical publications are obtainable from the National Institute for Metallurgy, Private Bag X3015, Randburg, 2125 South Africa. For those reports that are out of print, photocopies can be supplied at a nominal charge. The papers and patents are not available from NIM: the papers can be consulted in the journals or books in which they were published, and the patents are obtainable from the Patent Office, 25 Southampton Buildings, London WC2A 1AY, England. The publications that have been included since the last issue of this list (Report 2013) are marked •.
