a Young Girl, due to "complaints about its sexual content and homosexual themes." This version "includes passages previously excluded from the widely read original edition.... Some of the extra passages detail her emerging sexual desires; others include unflattering descriptions of her mother and other people living together." After consideration, it was decided a copy of the newer version would remain in the library and classes would revert to using the older version. In 2013, a similar controversy arose in a 7th grade setting in Northville, Michigan, focusing on explicit passages about sexuality. The mother behind the formal complaint referred to portions of the book as "pretty pornographic." The American Library Association stated that there have been six challenges to the book in the United States since it started keeping records on bans and challenges in 1990, and that "[m]ost of the concerns were about sexually explicit material". Authenticity As reported in The New York Times in 2015, "When Otto Frank first published his daughter's red-checked diary and notebooks, he wrote a prologue assuring readers that the book mostly contained her words". Although many Holocaust deniers, such as Robert Faurisson, have claimed that Anne Frank's diary was fabricated, critical and forensic studies of the text and the original manuscript have supported its authenticity. The Netherlands Institute for War Documentation commissioned a forensic study of the manuscripts after the death of Otto Frank in 1980. The material composition of the original notebooks and ink, and the handwriting found within them and the loose version were extensively examined. In 1986, the results were published: the handwriting attributed to Anne Frank was positively matched with contemporary samples of Anne Frank's handwriting, and the paper, ink, and glue found in the diaries and loose papers were consistent with materials available in Amsterdam during the period in which the diary was written. The survey of her manuscripts compared an unabridged transcription of Anne Frank's original notebooks with the entries she expanded and clarified on loose paper in a rewritten form and the final edit as it was prepared for the English translation. The investigation revealed that all of the entries in the published version were accurate transcriptions of manuscript entries in Anne Frank's handwriting, and that they represented approximately a third of the material collected for the initial publication. The magnitude of edits to the text is comparable to other historical diaries such as those of
