About the World Directory of Crystallographers

The World Directory of Crystallographers and of Other Scientists Employing Crystallographic Methods (WDC) is periodically published by the IUCr as a resource providing contact details and scientific interests of active crystallographic researchers.

Up to the 8th edition in 1990 only paper copies were produced but subsequently the situation changed considerably due to the rapid growth of computer networks. The 9th edition (WDC9) was the first one also accessible over the Internet. The entries were stored in the form of a database. Since the IUCr had by that time established its own format for crystallographic information, it was decided to use the same format, i.e. to store the data as STAR files (the same format used for Crystallographic Information Files, CIF). From these a qi database was created in 1995 to enable WDC to be interrogated through the Web and Tex files were created for the printing of the paper edition of the directory.

Internet use of the database has been very successful. The number of interrogations grew rapidly and a new relational database implementation was launched at the end of 2001. Since that time no hard-copy edition has been published.
