In this MA thesis, the issue regarding the terminology related to participatory community archives is illustrated by providing several different terms which are used to refer to them. A brief overview of their history and development is provided, their definition is explained from several different viewpoints, as well as their similarities and differences about their characteristics and principles. Furthermore, different models of collaborations with traditional heritage institutions and with the community are displayed, as well as the contributions from individuals in all their activities. The role of activism as the main motivation behind their creation and their development is presented, and the importance of educating, not only the society, but archivists as well, is emphasized. The advantages and disadvantages of digital technologies, especially archiving in the cloud, are explored, in addition to highlighting the issues that affect their sustainability. Moreover, the juridical limitations in Croatia which have a negative impact on their development and activities are portrayed, as well as the adverse effect they have on their visibility and potential partnerships. Through several examples, the activities, importance and the causes of their founding are illustrated. Finally, the results of the survey conducted among participatory community archives from Croatia and abroad are analysed and the overall conclusion is given.
