“At present time the SIC code is used for the classification of industry.  That code does not provide sufficient distinction for many non-traditional, and hi-tech industries.  The DTIC schedule is used for the classification of technology areas of interest to the U.S. DoD.  The Library of Congress book classification schedule is used exclusively for books, and also does not explicitly cover recent advances and novel technologies.  
TechExpo has a need to classify industry, engineering and life/medical sciences using a single schedule.  There are of course many ways to slice the pie, and it would be impossible to satisfy everyone's desires.  However, a logical classification schedule can be formed.  The idea is not to form too many categories and sub-categories as to differentiate subspecialties, yet to have enough categories to distinguish, where necessary, among diverse fields.  The schedule is not unique, and a company may be assigned more than a single classification code. “
