The Virtual Archive „Marienthal“ was created as part of the website project Die Arbeitslosen von Marienthal, led by Prof. Reinhard Müller at the Archive for the History of Sociology in Austria. It provides access to unpublished documents related to Marienthal and the seminal 1933 sociographic study Die Arbeitslosen von Marienthal, which examined the effects of long-term unemployment. The archive focuses on making diverse sources available to students, educators, researchers, and the general public. Most sources are available as facsimiles. The archive is complemented by additional collections, including visual materials in the Virtual Image Archive „Marienthal“ and the Virtual Image Collection „Marienthal-Gramatneusiedl“.

In 1900, The Exhibit of American Negroes at the Paris Exposition stood out as a pioneering sociological presentation. W.E.B. Du Bois and his colleagues used advanced sociographic and sociological methods to visualize progress as well as oppression of African Americans. Particularly innovative were the data portraits, which combined statistical and aesthetic forms of representation to visualize social and historical realities in a groundbreaking way.

The archive comprises over 450 volumes of interviews, questionnaires, observations and statistical information. It documents the social and economic life of London, highlighting all of its contrasts, complexities and contradictions. The archive also takes us „behind the scenes“ of the Inquiry itself, showing how Booth and his research team developed new methodologies and techniques in what is now recognised as a key milestone in the development of social research techniques.

The Down Survey of Ireland (1656–1658) was the first national land survey of its kind, conducted to facilitate the large-scale transfer of landownership from Irish Catholics to English Protestants following Oliver Cromwell’s military conquest. Overseen by William Petty, the surgeon-general of the English army, the survey aimed to provide an accurate mapping of forfeited land. The online archive brings together all surviving maps from this project, digitizing and making them publicly accessible. It consists of two main sections: Down Survey Maps, which includes maps at parish, barony, and county levels along with original written descriptions (terriers), and Historical GIS, which integrates these maps with contemporary sources (e.g., Books of Survey and Distribution, 1641 Depositions, 1659 Census) in a Geographic Information System (GIS). The data has been georeferenced with 19th-century Ordnance Survey maps, Google Maps, and satellite imagery, offering insights into historical land distribution and its long-term impact.
