School libraries are libraries that provide services to meet the information needs of students, parents, teachers, administrators and other school staff. As the main function, these libraries support the curriculum. These libraries, which take place in the periods of learning in individuals' lives, are also places where current technology and facilities are provided and services and environments are provided in accordance with the expectations and characteristics of the target audience. The school libraries in Turkey are planned to be transformed into social learning places within the scope of the enriched libraries project (z-kutuphane) coordinated by the Ministry of Education. In this regard, it is seen that the school libraries are equipped with technological facilities and streamlined furnishings. In this study, it is aimed to describe the current situation and usage of z-libraries in schools in Cankaya district of Ankara. For this purpose, 12 z-libraries in schools at Cankaya, Ankara were analyzed. In the context of this case study, which is one of the qualitative research methods, data were collected through semi-structured interviews and observations with school principals, assistant principals, and teachers in charge of the library. The study results reflect that z-libraries are spatially compliant with the standards, however, this case may vary depending on the number of students. It was understood that compliance with international programs, teacher and principal awareness, and projects are the factors that provide efficient and expected use of z-libraries. On the other hand, it has been detected that there are problems regarding the sustainability of these libraries. In the last part of the study, recommendations and future studies that can be conducted are addressed.
