This article can be read as an Editorial for the first issue of the Journal of Catalan Intellectual History (JOCIH) in its new stage at de Gruyter Open. It offers, first, a methodical review of the concept, roles, and trends of intellectual history in the 20th century. Next, it looks into the particular Catalan tradition, historiography, and cultural analysis to position the aim and the role of the Journal with regard to similar initiatives. It tries to give an answer to the crisis of intellectual history as a discipline, at the end of the past century. The third part of the article describes some of the available resources. The fourth section introduces the contents of the present issue, focussing on the construction of a collective identity and the literary engagement of Catalan writers between 1920 and 1980, either in their country or in exile. The Notes of the present issue highlight the importance of technology, natural language processing, and Semantic Web developments in carrying out contemporary research in this field.
