The database contains references to the papers, data files and links to the Internet resources related to measurements and calculations of the optical constants in the wavelength interval from X-rays to radio domain. ... References to some useful books and reviews on the subject (e.g. the classical handbooks edited by E.D.Palik) and links to Internet collections of optical constants and personal WWW pages with related software were also placed in the database.

... Every year, more and more journals are switching from mailing paper copies to subscribers to putting material on the Internet either for free or via password-protected access. The primary driving force behind this is simple economics: the cost of publishing material online is a minuscule fraction of the expense of printing articles in a paper journal and mailing it. The majority of people over 40 greeted the advent of online journals with much sadness and even some derision. ...
