There was space here on work book cards for notes by the employment office. In box 17, for example, an entry was made as to whether the “green slip” or “gray slip” had been sent to the main card index relating to foreigners at the Reich Ministry of Labor. Exactly what had to be entered in the other boxes is not known, however, as this section was left blank on all the cards that have been looked at so far. If you know anything else about these fields, please send your feedback to eguide@arolsen-archives.org.
