The doctoral thesis analyses and discusses the publishing potential of the Croatian Natural History Museum(CNHM), the central institution ofCroatian natural history, and how its editions of geological topics can contribute and improve the popularisation of the Museum, geosciences and geological heritage.Aims of this research were firstlyto examine whether and how CNHMs publications on the geological subject can popularise the Museum, then how to better popularise geology as ascience and the Croatian geological heritage as well, and to examine the possibilities of involving geology in the school education of young people. The research covers CNHMs publications published in the period from the Croatian independence, from 1991 to 2017. It showed that in the observed period, CNHM published 159 publications, most of them – 93 are geological and geological-biological publications. In percentages, 58% were on the geological theme (47% of which were geological topics and 11% of geological-biological topics) and 42% on the biological theme. Within geological and geological-biological publications, 33% are in English. Out of the total published publications, 52% were available for shopping in the museum shop and the museum internet shop during the research time. Due to their content – diversity of topics and connection with attractive geological destinations packed in quality design with reasonable price CNHMs geological publications can contribute even more to popularization of museums, geology and geological heritage. Their potential impact on the geological education of young people is also quite relevant, but has been unused. The apparent primary obstacle to the full realization of the potential of CNHMs geological publications is the noticeably weaker visibility of this segment of CNHM’s activities, mostly recognized in public for its exhibition but not publishing activities. An additional obstacle is the low visibility of geology as a science in public, partly due to the lack of a proactive, entrepreneurial approach to HPM activities. The more visible publishing activity of the HPM can be achieved both through cooperation in the creative and cultural industries and within the heritage sector and thus gain importance. CNHM publications on geological heritage also can promote Croatian geological heritage sites by applying the creative industrybusiness concept. It means that geotourism in Croatia can be a stimulating platform for developing local communities as attractive geological destinations through real synergy, thus contributing their economical prosperity. Finally, to achieve a total contribution of geological science to the development of Croatian society, it is vital to popularise geology and start with geological education as early as elementary school age. It is precisely in this segment where CNHM publications with geological content can and should play a significant role.
