Metals database

Dear Dr. Duax

I notice in the IUCr Newsletter Vol. 8, No. 2 a paragraph concerning 'Metals in the PDF'. Besides the data bases cited in the article, the most specific collection of data on metallic substances (metals and intermetallic compounds) is CRYSTMET, distributed on CD by John Rodgers (rodgers@snd.cisti.nrc.ca) at a reasonable price for academics. This data base is a valuable tool for people working in the field and among other facilities it contains in graphical form the powder pattern of each compound. For many years, I have been an enthusiastic user and I recommend it to everyone interested in intermetallics.
