1991, Holocaust deniers Robert Faurisson and Siegfried Verbeke produced a booklet titled "The Diary of Anne Frank: A Critical Approach", in which they revived the allegation that Otto Frank wrote the diary. Purported evidence, as before, included several contradictions in the diary, that the prose style and handwriting were not those of a teenager, and that hiding in the Achterhuis would have been impossible. In 1993, the Anne Frank House in Amsterdam and the Anne Frank Fonds in Basel filed a civil lawsuit to prohibit further distribution of Faurisson and Verbeke's booklet in the Netherlands. In 1998, the Amsterdam District Court ruled in favour of the claimants, forbade any further denial of the authenticity of the diary and unsolicited distribution of publications to that effect, and imposed a penalty of 25,000 guilders per infringement. Censored sections Since the original publication, several sections of Anne's diaries which were initially edited out have been revealed and included in new editions. These contain passages relating to her sexuality, exploration of her genitalia, and her thoughts on menstruation. Following the conclusion of an ownership dispute in 2001, new editions have also incorporated pages removed by Otto Frank prior to publication which contain critical remarks about her parents' strained marriage and discuss her difficult relationship with her mother. Two additional pages which Anne had pasted over with brown paper were deciphered in 2018, and contained an attempt to explain sex education and a handful of "dirty" jokes. Legacy On 3 May 1957, a group of Dutch citizens, including Otto Frank, established the Anne Frank Stichting in an effort to rescue the Prinsengracht building from demolition and to make it accessible to the public. The Anne Frank House opened on 3 May 1960. It consists of the Opekta warehouse and offices and the , all unfurnished so that visitors can walk freely through the rooms. Some personal relics of the former occupants remain, such as movie star photographs glued by Anne to a wall, a section of wallpaper on which Otto Frank marked the height of his growing daughters, and a map on the wall where he recorded the advance of the Allied Forces, all now protected behind acrylic glass. The House provides information via the internet and offers exhibitions. From the small room which was once home to Peter van Pels, a walkway connects the building to its neighbors, also purchased by the Foundation. These
