Introduction: This study examines data handling and data ethics in library learning analytics research projects involving the use of data about students as library patrons, alongside a baseline evaluation of the benefits of library learning analytics to libraries practicing it. Methods: Citations were gathered via citation chain aggregation from the original Value of Academic Libraries report, then winnowed to projects with English-language artifacts documenting them, collection and/or analysis of library data about students, and a research question about the contribution of student library use to student success. Results and Discussion: Much of this research is reaching publication despite not employing best practices nor documenting respect for human-subjects research ethics, library-specific privacy and confidentiality ethics, and student data-privacy expectations. Very few projects create direct benefits to libraries. This result would not be possible without gaps or lapses in editorial processes, peer review, and upstream research guidance and ethics reviews. Conclusion: Ethics reforms are required at all stages of research and publication to prevent further unethical exploitation of patron data.
