The project aimed to digitally preserve, transcribe, and enrich a post-war research archive compiled by historian Ben Sijes between 1946 and 1951. This  collection formed the empirical basis for Sijes’ study \n<a href=\"https://upload.wikimedia.org/wikipedia/commons/a/aa/Ben_Sijes_-_De_Razzia_van_Rotterdam_10-11_november_1944_-_Rijksinstituut_voor_Oorlogsdocumentatie_-_'s_Gravenhage_1951.pdf\" target=\"_blank\">\n  <i>De razzia van Rotterdam, 10-11 november 1944</i> (Nijhoff, 1951).\n</a><br><br>\n\nSijes’ research examined the large-scale razzias carried out by the Nazi occupation regime in and around Rotterdam in November 1944, during which approximately 52,000 men were forcibly removed from their homes and subjected to forced labour in the Netherlands and Germany. <br><br>\n\nThe aim of the 2025-2026 digitisation project was to make this historically significant material sustainably accessible and reusable for both researchers and a broader audience. By applying contemporary digitisation and data enrichment methods, the project enables new forms of research, preservation, and presentation. <br><br>\n\nAs part of this work, the questionnaires used by Sijes were not only digitised as images but also processed into a structured, machine-readable dataset. Using automated layout recognition and text recognition techniques, the project produced structured transcriptions of the questionnaire forms, linking the original survey questions to the transcribed handwritten responses of participants. This structured representation makes it possible to analyse the questionnaire data systematically and to connect individual responses. <br>\n\n <br><b>Creator</b> <br>\nThe dataset collection was created by the NIOD Institute for War, Holocaust, and Genocide Studies (hereafter: NIOD). Founded in 1945, NIOD serves as the national institute for the documentation and study of war and occupation in the Netherlands. The institute functions both as an archival repository and as a research institute, conducting interdisciplinary research on war, mass violence, and genocide. <br><br>\n\nNIOD manages approximately 400 archives and collections, together comprising around 2,500 linear meters of material related to twentieth-century war and mass violence. Through digitisation projects such as 'Razzia van Rotterdam Digitaal', NIOD aims to ensure the long-term accessibility and reuse of its collections for research, education, and public engagement. <br>\n\n<br><b>Razzia van Rotterdam Collection</b><br>\nSijes’ research collection, <a href=\"https://proxy.archieven.nl/298/5597A61176CFBC24E0538A77ABC28183\" target=\"_blank\" rel=\"noopener noreferrer\"><i>Collectie Onderzoekingen 258: Razzia van Rotterdam</i></a>, consists of nearly six linear meters of documentation gathered between 1946 and 1951. The collection includes completed questionnaires from respondents of diverse social backgrounds, personal letters, correspondence with governmental and private institutions, and written reports of interviews and personal conversations.<br><br>\n\nSijes personally conducted interviews, distributed hundreds of questionnaires, and maintained correspondence with a wide range of contemporaries, including resistance members, mayors, civil servants, police officers, company employees, and victims of the razzia and their relatives. He considered these interviews and questionnaires an important supplement to diaries and letters. <br><br>\n\nBecause the collection was assembled shortly after the events of November 1944, it provides both direct insight into individual wartime experiences and valuable evidence of early post-war research practices at the Rijksinstituut voor Oorlogsdocumentatie (RIOD), the predecessor of NIOD. <br>\n\n <br><b>Contents</b> <br>\n\nThe R2D dataset collection consists of three main components. <br><br>\n\n<u> 1.\tPersons index with demographical data </u> <br>\n\nThis file contains tabular data with personal and demographic information on individuals surveyed or interviewed for Ben Sijes’ research project (1946-1951). The dataset was originally compiled during earlier research based on NIOD’s archival collection 'Collectie Onderzoekingen 258: Razzia van Rotterdam' and later enriched with additional information.  <br>\n\nDuring the 2025–2026 'Razzia van Rotterdam Digitaal (R2D)' project, the dataset was cleaned, manually checked, and expanded. Where possible, links were added to HTR transcriptions from NIOD’s digitisation project and to corresponding personal entry pages on Oorlogsbronnen.nl.  <br>  <br>\n\nContents: <br>\n•\tReadme file: PersonsIndex_R2D_2026_Readme (.txt) <br>\n•\tPersons index table: PersonsIndex_R2D_2026 (.csv) <br>\n\n<u> <br> 2.\tTranscriptions of correspondence, interview reports, and questionnaires (1946-1951)</u> <br>\n\nThe folder 'Transcriptions of correspondence, interview reports, and questionnaires' contains automatically generated transcriptions of historical handwritten and typescript documents. The transcriptions were created using Handwritten Text Recognition (HTR) and Optical Character Recognition (OCR) and are provided in Alto XML format, preserving both text and layout of the original records. <br><br>\n\nContents: <br>\n•\tReadme file: TextTranscriptions_R2D_2026_Readme  (.txt) <br>\n•\t29.624 Transcriptions in Alto XML format organized, in 346 different folders (.xml) <br>\n\n<u><br> 3.\tStructured transcriptions of questionnaires (1946-1951)</u>  <br>\n\nThis folder contains machine-generated structured transcriptions of the questionnaire forms used by Sijes, including both blank and completed forms. The questionnaires were processed using automated layout and text recognition to identify elements such as question numbers, answer fields, and document structure. <br><br>\n\nThe results are provided in JSON format, making the data machine-readable and suitable for further computational processing and/or analysis. Each file contains information about the questionnaire structure and links questions to the transcribed handwritten responses of participants. <br><br>\nContents: <br>\n•\tReadme file QuestionnaireTranscriptions_R2D_2026_Readme (.txt) <br>\n•\t11.944 JSON files containing questionnaire structure and transcribed text in 180 folders (.json) <br>\n\n <br><b>Access</b> <br>\nNIOD seeks to promote broad access to and responsible use of the data it collects and publishes for academic research purposes.
