A busy writing day: 28 September 1942 
 
 In the afternoon of Monday 28 September 1942 workmen were busy removing the office toilet, immediately below the secret annexe, so any sound from the hiding place was dangerous and had to be avoided at all costs. Anne was writing. In her diary Anne pretended that she was corresponding with a number of imaginary friends, and that day she wrote a total of four “diary letters”: to her whole circle of imaginary friends, to Kitty, to Pien and to Loutje. 
 
 On that day she also leafed through her entire diary and added comments to no less than 18 earlier “diary letters”. She wrote additions to photo captions, to a letter from her father and to a letter from her friend Jacqueline van Maarsen that she had earlier stuck into her diary. What is more, Anne also wrote of how afraid she was that the people in hiding would be discovered, and how much support her diary gave her. She made a list of twelve signs of beauty and assessed the extent to which she lived up to them. It all goes to show that on that day Anne was closely scrutinising herself, her own sexuality and the world around her. ||||| 1. What is written on the revealed pages? 
 
 "I'll use this spoiled page to write down 'dirty' jokes", wrote Anne on 28 September 1942. At that time she had been in hiding in the secret annexe for barely two months. In an attempt to save what she saw as the 'spoiled' page of her beloved diary, she first listed four 'dirty' jokes. From these jokes Anne moves on to the subject of sex education, pretending that she has to give it to someone. Read more. 
 
 2. How did you discover the content of the covered pages? 
 
 In 2016 the diaries of Anne Frank were photographed as part of a check on their condition. The two covered pages were also photographed then. In fact a photograph was made through the covered pages, and thanks to digital technology the text became visible. 
 
 3. Why did Anne Frank cover up the pages? 
 
 We don't know. But what we do know is that Anne regularly reread her diary entries and made changes to them. For example in one of her diary entries of 28 September 1942 Anne wrote that with hindsight she viewed certain 'things' from a 'new standpoint'. 
 
 A number of times Anne explicitly wrote that she was afraid that other people in the secret annexe would read her diary. This mainly concerned passages in which the people themselves appear. On 21 September 1942, for example, she wrote that Mrs Van Pels wanted to read her diary. 
 
 Anne may also have been afraid of this when she wrote on 3 October 1942: "Daddy is grumbling again and threatening to take away my diary. Oh, horror of horrors! From now on, I'm going to hide it." 
 
 4. Did Anne cover up any more pages of her diary? 
 
 No, these were the only two pages that were covered. 
 
 5. Is this the first time that new texts by Anne Frank have been discovered? 
 
 No, in 1998 three loose pages, with five written sides, of Anne's diary papers came to light. These are included in the reissue of the critical edition by the NIOD Institute for War, Holocaust and Genocide Studies (2001). 
 
 6. Anne covered up the pages for a reason. Is it right for you to publish these pages? 
 
 Of course we asked ourselves, together with the other organisations involved, the question of whether it was right to publish a text that Anne had covered up. After careful consideration we arrived at a positive answer. 
 
 The diary papers of Anne Frank are world-famous. Millions of people have read her diary and visited the Anne Frank House . The diary papers have UNESCO world heritage status. So there is also a major public interest connected with the publication of this new text. The text also offers us the possibility of gaining a better insight into the way the diary papers were created. A major academic interest is served by this. 
 
 The diary of Anne Frank is a world heritage object with great historical value, and this justifies research into it. Research into Anne Frank's qualities as a writer means research into the process of deliberation and of writing and deleting, as this can be deduced from her diary texts. Rejected versions are just as important for insight into her working method as passages that were added. The covered sections of the text are part of the object of research. 
 
 Texts from Anne Frank's diary papers that she did not herself intend for publication have been published earlier, at various times. That already occurred in the publication arranged by her father in 1947, and later in the compilation of the critical education by the NIOD Institute for War, Holocaust and Genocide Studies, which was published in 1986 and republished in 2001 after the discovery of five new diary pages. 
 
 We can well understand the standpoint of people who think that we should not have published the text, but on the basis of the above arguments we have come to a different conclusion. We realise that not everyone will adopt a different standpoint because of this, but we hope that in this way we have shown that we did not take this decision lightly and that it was taken with great care. ||||| A video shows the text underneath two taped off pages from Anne Frank's diary during a press conference at The Anne Frank Foundation's office in Amsterdam, Netherlands, Tuesday, May 15, 2018.

 AMSTERDAM (AP) — Researchers using digital technology deciphered the writing on two pages of Anne Frank's diary that she had covered over with brown masking paper, discovering four risque jokes and a candid explanation of sex, contraception and prostitution. 
 
 "Anyone who reads the passages that have now been discovered will be unable to suppress a smile," said Frank van Vree, director of the Netherlands Institute for War, Holocaust and Genocide Studies. "The 'dirty' jokes are classics among growing children. They make it clear that Anne, with all her gifts, was above all also an ordinary girl." 
 
 Anne, age 13 at the time, wrote the two pages on Sept. 28, 1942, less than three months after she, her family and another Jewish family went into hiding from the Nazis in a secret annex behind a canal-side house in Amsterdam. 
 
 Later on, possibly fearing prying eyes or no longer liking what she had written, she covered them over with brown paper, and their content remained a tantalizing mystery for decades. 
 
 It turns out the pages contained four jokes about sex that Anne herself described as "dirty" and an explanation of women's sexual development, sex, contraception and prostitution. 
 
 "They bring us even closer to the girl and the writer Anne Frank," Ronald Leopold, executive director of the Anne Frank House museum, said Tuesday. 
 
 Experts on Anne's multimillion-selling diary said the newly discovered text, when studied together with the rest of her journal, reveals more about her development as a writer than it does about her interest in sex. 
 
 Anne wrote candidly in other parts of her diary about her burgeoning sexuality, her anatomy and her impending period. Those passages were censored by her father before the diary was first published in 1947 but became available in more recent unabridged editions. 
 
 Leopold said the newly deciphered material provides an early example of how Anne "creates a fictional situation that makes it easier for her to address the sensitive topics that she writes about." In her diary, for example, she addressed entries to a fictional friend named Kitty. 
 
 The institutions involved in the latest research said that because of copyright issues, it is unclear whether the passages will be incorporated into new editions. 
 
 The deciphering was done by researchers from the Anne Frank museum, the Institute for War, Holocaust and Genocide Studies and the Huygens Institute of Netherlands History. 
 
 They photographed the pages, backlit by a flash, and then used image-processing software to decipher the words, which were hard read because they were jumbled up with the writing on the reverse sides of the pages. 
 
 In the passage on sex, Anne described how a young woman gets her period around age 14, saying that it is "a sign that she is ripe to have relations with a man but one doesn't do that of course before one is married." 
 
 On prostitution, she wrote: "All men, if they are normal, go with women, women like that accost them on the street and then they go together. In Paris they have big houses for that. Papa has been there." 
 
 Anne wrote her diary while she and her family hid for more than two years during World War II. The family went into hiding in July 1942 and remained there, provided with food and other essentials by a close-knit group of helpers, until Aug. 4, 1944, when they were discovered and ultimately deported to Auschwitz. 
 
 Only Anne's father, Otto Frank, survived the war. Anne and her sister died in Bergen-Belsen camp. Anne was 15. 
 
 After the war, Otto Frank had his daughter's diary published, and it went on to become a symbol of hope and resilience that has been translated into dozens of languages. 
 
 The house where the Franks hid was turned into a museum that is one of Amsterdam's most popular tourist attractions. ||||| The covered pages 
 
 The covered pages were photographed during a regular check on the condition of the diaries of Anne Frank in 2016. Thanks to image processing technology the text could be deciphered. The texts that are being published for the first time today do not stand in isolation; they form a part of the diary entries that Anne Frank began on 12 June 1942. The texts that have now been revealed are included in the academic research into the diaries of Anne Frank and her development as a writer that the Anne Frank House has been carrying out together with the Huygens Institute for the History of the Netherlands since 2010.
– Only two pages of Anne Frank's diary remain unread—or, remained. The Anne Frank House on Tuesday revealed that it had managed to read the pages, which a then 13-year-old Anne wrote on Sept. 28, 1942, and subsequently covered over with brown masking paper, keeping the pages' contents a tantalizing mystery for decades. It turns out the pages contained four jokes about sex that Anne herself described as "dirty." "I'll use this spoiled page to write down 'dirty' jokes," Anne wrote, then went on to list them; the Anne Frank House didn't specify what the jokes were, and because of copyright issues, it is unclear whether the passages will be incorporated into new editions. But the institution did share some of what it says were 33 lines about sex education and prostitution also on the pages. On prostitution, she wrote: "All men, if they are normal, go with women, women like that accost them on the street and then they go together. In Paris they have big houses for that. Papa has been there." To reveal the words, researchers photographed the pages, backlit by a flash, and then used image-processing software to decipher the words, which were hard to read because they were jumbled up with the writing on the reverse sides of the pages. "Anyone who reads the passages that have now been discovered will be unable to suppress a smile," said Frank van Vree, director of the Netherlands Institute for War, Holocaust, and Genocide Studies, per the AP. "The 'dirty' jokes are classics among growing children. They make it clear that Anne, with all her gifts, was above all also an ordinary girl."
