 Ronald Reagan was one of five American Presidents to have kept a consistent diary as President, and the only one to do so each day, never neglecting an entry (even when he was in the hospital recovering from his assassination attempt).The diaries number five volumes of thick, maroon, leather-bound books, normally kept in the White House residence, written in simple, childlike prose, with many misspellings.Former First Lady Nancy Reagan made the diaries available to be transcribed in 2005, and the Reagan Library Foundation partnered with HarperCollins to print them in 2007.
