Release 1995

by Syb Gorter and Deane K. Smith


The World Directory of Powder Diffraction Programs is a continuing project with the goal to identify and catalogue all the programs available for powder diffraction analysis. It is a joint project of Syb Gorter of the Netherlands and Deane K. Smith of the USA and is sponsored by the Comission on Powder Diffraction of the International Union of Crystallography. The main collection point is Leiderdorp, the Netherlands.

The 1995 list of programs contains 670 program listings categorized into 22 areas of activity and 6 subgroups. The program listing includes information on the language, platform, distribution and cost where known. In addition there is an Appendix with the addresses of the program authors and an extensive list of references. E-mail addresses and Fax/Phone numbers are included where known.

This list will continue to be maintained with the help of program authors and users. There are forms available to supply program information for additional entries for the WDPDP. All the information requested on the form should be supplied for the entry to be complete and usefull to others. The completed forms should be sent to Syb Gorter to the address below.

In addition to the maintenence of the WDPDP, Syb Gorter operates the Program Exchange Bank where many of the programs in the WDPDP are available on request. Programs currently available by this route are indicated in the WDPDP by "PEB" in the author column. Programs may be acquired by ftp or on some specific media. For the latter way a charge has to be paid to cover the costs.


The cost of the WDPDP95 is US$50 covering printing, mailing from the Netherlands (air mail) and currency exchange. When payment is in cash a discount of US$15 is available. Your address on file at the PEB will assure you of information on updates. An order form will be sent on request or the one below may be used. Payment should accompany the order form. An invoice will be enclosed on delivery. Direct orders may be made at any time to the Program Exchange Bank.
