For collected references to papers and data files, please, follow the links to the groups of materials given above!   More data and information may be found in other databases, published collections of optical constants and books and reviews on the subject listed below. Of some interest may be the tools of the Kramers-Kronig analysis, the Effective Medium Theory and light scattering codes available in Internet.

To cite the database one should use the reference:

The current state of the database and our future plans are described (with some illustrations) in:
