Interviews with former members of the Arbeiders Jeugd Centrale with as a common thread their personal experiences, and the possible role of the AJC in this, during World War II. The interviews are the basis for the book by Geertje Marianne Naarden (Amsterdam, 1979), 112 audio cassettes of which (as yet) 24 have been digitised. The cassettes mainly feature interviews with former members of the Arbeiders Jeugd Centrale (AJC), with an emphasis on their experiences during World War II and any role the AJC played in it. The interviews are the basis for the book Onze jeugd behoort de morgen…: de geschiedenis van de AJC in oorlogstijd by Geertje Marianne Naarden (Amsterdam, 1989). All interviews were conducted by Geertje Marianne Naarden, accompanied in part by co-interviewer Ad van Moock. Besides the interviews, some cassettes contain a radio broadcast, a work meeting, an AJC reunion, a lecture with discussion afterwards and some group meetings. 1 interview was done by Rie Spanjer for her book De AJC dat waren wij . This interview was also used by Naarden as a source for her book Onze jeugd behoort de morgen…: de geschiedenis van de AJC in oorlogstijd .

The interviewees are all former AJC members. The interviews were held on behalf of De Kok’s research into the history of the Dutch Workers’ Youth Central, in cooperation with the Stichting Onderzoek AJC.
Among those interviewed are a number of people who are known in other contexts: the historian Frits de Jong Edz. (1919-1989), the photographer Aart Klein (born 1909), the secretary of the Stichting Onderzoek AJC Ad van Moock and the political scientist/demographer Philip van Praag sr. (born 1914). The Dutchman Meilof was one of the editors of the book De AJC… dat waren wij. Herinneringen van oud-leden, Haarlem:
Stichting Onderzoek AJC, 1985. The interviews with Klein are only partly about his experiences in the AJC; they mainly deal with his life as a photographer between about 1930 and 1970.
De Kok and Peter Mol conducted the interview with Van der Kramer in January 1991. Besides his experiences in the AJC, the interview focused on the (8mm) amateur film he made for the AJC in 1937, which featured the May 1 celebrations in Zaandam and the SDAP election campaign that year.
