Metadata quality is directly related to the quality of services provided by digital libraries. The paper presents results from evaluating the metadata quality of the IPL (www.ipl.org). Two evaluation methods were used: a preliminary automatic evaluation and a human involved evaluation using a survey. The automatic evaluation was focused on the completeness of major IPL metadata fields. The human evaluation asked evaluators to judge the accuracy, completeness, consistency, functionality and usefulness of IPL metadata fields. Qualitative feedback from evaluators provided us an in depth picture of the IPL metadata quality. We also compared results from the automatic evaluation and the human evaluation.
