The “Tygodnik Ilustrowany”, one of its aims being to inform about world events and to collect and popularize historical mementoes during the period of historical transformations, focused its efforts on documenting changes. Publications that appeared in “Tygodnik Ilustrowany” between August 1914 and August 1915 can be divided into sentimental-emotional texts and information items. The “information hunger” of the readers was first of all satisfied by informative publications. The diversity of forms offered, both written (information texts, calendars of events, documents, testimonies of event participants, both by civilians and soldiers) and illustrative (maps, photo stories, single photographs), produced accounts, which, going beyond the strictly historical framework, nevertheless preserved historically significant events, occurrences or information items. For the weekly’s editors it was more important, rather than document “great history”, to record in their periodical the “daily history” and social responses to its events, which makes the “Tygodnik Ilustrowany” one of major sources to the historian studying World War I.
