In this qualitative research we explore different aspects of Spanish digital art catalogs, since they constitute a key element for the dissemination and research of cultural heritage. The considerable heterogeneity of the funds and managing agencies has resulted in a complex panorama, which has made the selection of a sample necessary. Although any of the examined digital model fully provides universal access to cultural heritage, ideas and practices that respond to the needs of a plural and diversified society emerge from them. The visibility of the positive aspects and those that can be improved show the potential of a tool able to responds to the needs of all audiences.
