In a climate of increasing costs and diminishing public budgets, public libraries, more than ever before need to show the positive difference they are making in communities and neighbourhoods. Outcome based evaluation assists in assuring that current programs and services are relevant. It helps to see the actual difference they make in patrons lives. It helps to ground institutions; removing them from the trap of sameness. Relevancy is obtained by proactively seeking, measuring and understanding how we make an actual qualitative contribution to a community. Provided by publisher.
