Analysis of technical efficiency is an important tool in management of public libraries. We assess the efficiency of 4660 public libraries established by municipalities in the Czech Republic in the year 2017. For this purpose, we utilize the data envelopment analysis (DEA) based on the Chebyshev distance. We pay special attention to the operating environment and find that the efficiency scores significantly depend on the population of the municipality and distance to the municipality with extended powers. To remove the effect of the operating environment, we perform DEA separately for categories based on the decision tree analysis as well as categories designed by an expert.
