The author ennumerates the basic evidences, held by individual communities, disctrict-boards and provincial presidency for Carniola and the emigration offices before the first World War. These evidences were: communal lists of emigrants, the registers of passports drawn out, the list of the absent recruits, district reports on the emigration, Carniola summary reports and the lists of passangers held by emigration offices. With all these evidences the author wishes to give the insight into a great variety of documents, which served the lower Austrian governmental bodies to follow, on the example of Carniola and Ljubljana itself, the process of emigration to America. In professional literature, we often find as the only source the published statistical data. The conservation of the archives in individual countries is the task of concrete surveys of all the materials held by the lower governmental bodies. Following the same sources, a numerical and rank emigration survey for the town of Ljubljana had been elaborated for the period 1892—1913, as far as emigration to America is concerned.
