The diary may be one mentioned by an engineer architect who wrote in his memoirs that he found the diary of a 14-year-old girl in the ruins. If it is though, part of it has been lost, according to a paper published by Dreyfus.
Silberklang said one name in the diary matches one in the archives and so the writer may be from that family. There isn't enough detail in the diary to be 100 percent sure.
Silberklang called the descriptions in the Warsaw Ghetto diary "very gripping, moving and deeply depressing.
