One of the most interesting materials in the Buenos Aires archive were seven squared notebooks with pasted-in contact prints of photographs of Warsaw, both from the prewar period as well as post-1945 images of the ruined city and its subsequent reconstruction, everything accompanied by the author’s commentary. Each notebook contained approximately 300 images. The whole material was scanned: each page and each photograph separately. Following the digitisation, the notebooks were sent back to Buenos Aires. The material served as basis for the publication The Chroniclers. Zofia Chomętowska and Maria Chrząszczowa, ed. Karolina Ziębińska-Lewandowska. Work is currently under way on digitising one selected notebook for online publication.
