Documents popularly known as the Torture Memos came to light a few years later. After digitization, paper memos and paper newsletters began to disappear. It was ideal for printing memos, letters, and spreadsheets. It also printed verbatim extracts from several of the leaked memos. No generally recognized document experts have positively authenticated the memos. In April 2009, President Obama released redacted versions of the Torture Memos. This led to claims that the memos were forgeries. He sent weekly memos, including a 26-page report in the summer of 1992. FBI strategy and modalities can be found in FBI inter-office memos. A pair of internal CRS memos were distributed, restricting report distribution. However, they were also backed up and transferred to paper memos. It is relied upon heavily by the subsequent "torture memos". Jack Goldsmith, the OLC's new head, had repudiated and withdrawn the Torture Memos. He had earlier advised agencies not to follow the three August 2002 memos. Flying paper aeroplanes (referred to as "interdepartmental memos") are used within the Ministry of Magic.
