I attach info from JCPDS

>>Subject: JCPDS Files

These people should contact the International Centre for Diffraction Data at 

    information@icdd.com
with their full snail-mail address to receive the catalog of products 
available.

The ICDD (formerly Joint Committee on Powder Diffraction Standards, JCPDS) 
"is a nonprofit scientific organization which collects, edits, publishes, 
and distributes powder diffraction data for the identification crystalline 
materials."  I am quoting the introduction of the catalog.
    "The Powder Diffraction File is a collection of single-phase X-ray 
powder diffraction patterns in the form of tables of characteristic 
interplanar spacings and corresponding relative intensities along with other 
pertinent physical and crystallographic properties.... the PDF is available 
on a wide variety of media... [and] has various subfiles of data which 
include minerals, metals and alloys, and forensic materials."  Most 
importantly, "information in the PDF is continuously reviewed and upgraded 
for accuracy and quality."
    The ICDD markets various search-match methods, related educational 
material, and specialized products including some which they do not produce. 
 They do produce the journal Powder Diffraction and also put on clinics in 
fundamental and advanced methods in both X-ray diffraction and X-ray 
fluorescence.

I am connected to the ICDD only as an interested (and grateful) scientist 
and do not stand to profit from spreading this information (i.e. this is not 
an advertisement).  Any mis-information conveyed above is solely my fault. 
 Interested parties should contact the Centre for the whole story (including 
prices!).
