In context of the cultural identity and regional studies, the article evaluates the contribution of researchers from Kurzeme Institute of Humanities, Liepāja University, into research and preservation of the historical and cultural heritage of Kurzeme region. The aim, the main tasks, the development of conception and the course of implementation of The Encyclopedic Dictionary of Kurzeme Culture (since 2012) are described as well as its thematic sections (biographies of the prominent personalities in literature and theatre, and the cultural values they have created after Latvia regained its independence). The examples give an insight into the dictionary’s content and provide the evidence for analysis of the main problems in material selection, development of the body, structure and content of the dictionary entries. The article also indicates the possible solutions in the future (development of other thematic sections, addition of audio and video recordings) and discusses the possibility of digitization of the dictionary in order to ensure its accessibility to large audiences.
