The second version of SSD (Surface Structure Database) appeared in early 1996, updating the first version of SSD, published in 1993. SSD-2 includes nearly 1000 structures (an increase of over 50%) published through mid-1995, as well as numerous software extensions and improvements.

SSD is an interactive PC-based database of experimentally determined surface structures. For maximum reliability and usefulness, the structures are critically selected to be completely solved, by any established technique. The database includes extensive information not only about atomic positions and bond lengths and angles, but also about experimental preparation, measurement and analysis methods.

The main features of SSD will be exhibited. They include an advanced search and display system, as well as an interactive 3D color visualization that has great flexibility. It is also possible to generate publication-ready color or gray-scale prints of any structure.
