Cataloguing constitutes the main instrument for heritage assessment and management around the world, and is central in heritage studies. In the context of the growing international protection of heritage since the 20th century and the irruption and implementation of digital tools, cultural heritage data bases (CHDBs) have emerged as the main systems in accounting for and monitoring heritage. In the framework of culture preservation, as a driving force of sustainable development, this article aims to analyse the origins and development of CHDBs in order to critically observe the current situation and outline future challenges for systems of cataloguing heritage with the growing relevance of its graphical documentation. In this context, a historical overview of the origin and development of the European inventories since the 18th century to the present is key to trace the development of catalogue systems and the impact of IT in this field. The study then focuses on immovable cultural heritage data bases (ICHDBs); with Spain as case study, it develops an approach to the current panorama, with a special focus on the conceptual evolution of catalogues. In conclusion, ICHDBs need to transcend both instrumental and institutional roles and, supported in new digital systems, become interactive and flexible tools that respond to current needs and encourage heritage education, knowledge, and reflection.
