In this article, using publications from the Jaunimo draugas magazine published in Vilnius and personal field research material, I seek to compare ethnographic material collected during field research and published ethnographic material and how these harmonise to reveal the particularities of youth leisure time in the historic Vilnius Region (1920–1939). After conducting a comparative analysis, it could be concluded that press publications cannot reveal all forms of youth leisure time, however, they do convey a strict diachronic perspective when identifying the modernisation of leisure time, which often omits the regional differences of this phenomenon. Having carried out this research, one can conclude that press publications can be important to ethnologists beyond just serving as an additional source that expands the limits of perception of field research data.
