This Technical Report establishes the performanceindicators for national libraries. It is also applicable to libraries with regional tasks and without a defined population to be served, as many of their evaluation problems correspond to those of national libraries.

The performanceindicators are of special interest for comparison over time within the same library. Comparisons between libraries are possible, if differences in the tasks and constituencies of the libraries are taken into account.

This Technical Report does not include performanceindicators for evaluating the outcomes or impact of library services either on individuals, on the communities that libraries serve, or on society at this time. Since this is an evolving area of performance measurement for libraries, such performanceindicators can be added at a later date.

This Technical Report is not intended to exclude the use of any performanceindicators which have not been specified herein.
