<span>Former US president Barack Obama's announcement of a</span><span> presidential memoir is not surprising. </span> <span>Out in November, the 796-page tome </span><span></span><span><em>A</em></span><span><em> Promised Land</em></span><span> follows a long line of former presidents reflecting on their experiences running one of the most powerful countries in the world.</span> <span>Obama's move is not down to sheer vanity. From Ulysses S Grant to George W Bush, presidential memoirs are an indispensable </span><span>source that provide</span><span> insights into the turbulent moments of the past and offer lessons for future generations of </span><span>leaders.</span> <span>That said, despite the importance of the work, some head of states </span><span>were not up to the literary task. A number of them were criticised for being selective about events and facts, while others had their work condemned </span><span>for being a snooze fest.</span> <span>Here are six former presidents who received a variety of reviews</span><span>.</span> <span>This is widely regarded as the finest presidential memoir to be released. According to US </span><span>historian Craig Fehrman, Grant </span><span>was "America's first full-blown fiction-loving president, and his fondness for novels clearly influenced his own writing".</span> <span>While military history buffs will savour Grant's descriptions of the battlefields during </span><span>the Civil War and the Mexican-American War (military maps are provided in some editions), what stands out to the common reader is Grant's sense of steely purpose. </span> <span>The memoir </span><span>is particularly poignant as it was written under physical pain and financial burden. Stricken with cancer of the throat, the 18th US president </span><span></span><span>wrote</span><span> the book to serve as a financial cushion for his family. </span> <span>Both volumes were released a year after his death in 1885.</span> <span>There are prolific writers and then there is Thomas Jefferson. The third president of the </span><span></span><span>US</span><span> reportedly wrote more than </span><span>70,000 letters throughout his lifetime, in addition to the </span><span>feat of </span><span></span><span>writing</span><span> the Declaration of Independence.</span> <span>With so much correspondence to his name, a tastefully edited selection of his letters </span><span></span><span>was</span><span> released. A mix of journal entries, notes and speeches, the collection </span><span>provides</span><span> an intimate snapshot of one of America's greatest intellectuals as well as an insight into the early years of a new</span><span> country.</span> <span>This is a </span><span></span><span>must-read</span><span> for political junkies and business leaders.</span> <span><em>Mandate for Change</em></span><span> has been praised as a game changer when it comes to presidential memoirs. A lot of that is down to the direct nature with which the 34th president approached the work. Perhaps down to his military training, the former Second World War </span><span>general jettisons the grandiosity surrounding the form and gets </span><span>into the nuts and bolts of presidential life. Covering his term between 1953-1956 in a stripped-down and no nonsense style, Eisenhower takes us into the mind of the presidency and explains how hard decisions are made through conviction and consensus.</span> <span>Published four years after resigning in disgrace, Nixon’s retelling of his 37th presidency was criticised by literary and political critics for seemingly everything, from being a ragtag assortment of thoughts to its defiant tone.</span> <span>In a withering assessment in the</span><span><em> </em></span><span><em>Foreign Affairs</em></span><span> magazine, Gaddis Smith panned Nixon's lack of scope: "He whines more and seems incapable of sustained analysis, irony, humour or any grasp of larger philosophical or historical dimensions. The book is less a thematic narrative than a collection of short memoranda chronologically arranged." Ouch. </span> <span>If that was not enough, the book was also subjected to a boycott campaign from groups angry at the crimes committed during Nixon’s presidency. With so much going against him, no wonder the book was a flop.</span> <span>This memoir arrived with all the fanfare of a Hollywood blockbuster. For the publishing industry,</span><span><em> My Life</em></span><span> was a watershed moment as </span><span>Clinton received what was then a record book advance </span><span></span><span>of</span><span> $15 million (Dh55m).</span> <span>For some readers and the political establishment, what they were looking for was how Clinton would address the Monica Lewinsky scandal that plagued his presidency. At a mammoth 1,008 pages</span><span>, the 42nd president dedicates no less than 30 pages to the ordeal with passages full of regret for all involved.</span> <span>The rest of the book is an engrossing look at how a saxophone-loving lawyer from a small </span><span>town went on to reach the highest office in the land. With Clinton keeping a journal for decades, the </span><span>memoir has </span><span>vivid recollections of meeting pivotal figures such as </span><span>South African leader Nelson Mandela and Colombian author Gabriel Garcia Marquez as well as handling of national emergencies such as the 1995 Oklahoma City terrorist bombing. </span> <span>Told with Clinton's trademark charm, </span><span><em>My Life</em></span><span> was a hit for the genre and went on to sell more than two million copies.</span> <span>Although</span><span> Clinton bested his father George Bush in the 1993 presidential election</span><span>, George W Bush defeated Clinton when it </span><span></span><span>came</span><span> to book sales. </span><span><em>Decision Points</em></span><span> comfortably surpassed </span><span><em>My Life</em></span><span>'s figures of 2.2 million copies sold within </span><span>the first two months of its release. </span><span>A lot of that was because of the momentous and often controversial nature of </span><span></span><span>the</span><span> Bush </span><span>presidency. At a crisp 486 pages and written with Texan directness, the 43rd president takes us through some of the biggest decisions he </span><span></span><span>made</span><span> over his two terms, ranging from his response to the 9/11 terrorist attacks, sending troops to Iraq and his administration's </span><span></span><span>handling</span><span> of the Hurricane Katrina crisis.</span> <span>The book did not elicit any real excitement from literary critics. The best they did</span><span> was call his prose "workman</span><span>like" and point to the fact that he comes across more relatable than expected.</span>
