The paper deals with the analysis of the cultural heritage of Croats in Bosnia and Herzegovina with a focus on the parish of Tolisa. The goal is to investigate the state, challenges and possibilities of digitization of cultural assets in this area with an emphasis on preservation and promotion through digital technologies. The main methods include the analysis of historical sources and a review of existing professional and amateur digitization projects. The results show that, although significant progress has been made so far in the digitization, there are numerous obstacles, including a lack of financial resources and professional staff. Through the example of the parish of Tolisa, the paper illustrates how specific cultural contents, such as registers, documents, local customs and traditions have already been digitized or are in the process of digitalization, but it is necessary to approach this process more systematically and professionally in order to ensure long-term preservation. The paper also highlights the importance of cooperation with international digitization institutions, which could facilitate access to resources and expertise. The conclusions suggest that the digitization of cultural heritage in Bosnia and Herzegovina, and especially in Croatian communities, represents an important strategy for preserving identity and cultural autonomy. It is suggested to continue and expand the existing projects, as well as the active involvement of local communities and international partners in order to ensure the sustainable development of digital heritage preservation. Digitization, although challenging, offers countless opportunities for the promotion of culture, the education of younger generations and the strengthening of cultural identity in today's digital age.
