Abstract / scope
ISO/TR 20983:2003 is applicable to all types of libraries in all countries. Limitations on the applicability of individual performance indicators are listed in the scope clause of the description of each indicator.
Indicators may be used for comparison over time for the services provided by the same library. Comparisons between libraries and services should only be made with caution, taking into account differences in the constituencies of the libraries, with good understanding of the indicators used, and careful interpretation of the data.
ISO/TR 20983:2003 does not include indicators for the evaluation of the impact of libraries either on individuals or on society.
