Developed by the Materials Laboratory at the University of Basque Country, Spain, the Bilbao Crystallographic Server supplies crystallographic programs and databases using the International Tables for Crystallography. The website is divided into six sections to help users gather their needed information efficiently. Within each section, users can chose specific criteria to find data and can view it with either the conventional or non conventional setting. The site provides articles discussing the Server that have been published in journals and conference papers. Several forums exist allowing researchers to converse with one another.

The Bilbao Crystallographic Server provides access to crystallographic programs, tools, and databases. The tools are grouped according to type: space groups retrieval; group-subgroup relations of space groups; representation theory applications; solid state theory applications; structure utilities; and subperiodic groups (layer, rod, and frieze groups retrieval tools). The Incommensurate Crystal Structure Database (ICSDB) provides access to four categories of data: general (chemical information and publication data); average structure (cell, symmetry, atom sites, and experimental data for the average structure); modulated structure (cell, symmetry, atom sites, and experimental data for the modulated structure); and modulation parameters (descriptions of the modulation, wave vectors, and atom sites modulations).
