Reflecting on South Korean history as a former president, Kim Dae-jung said, "When we examine history over the long term, those who dedicate themselves to the people are never truly defeated. They may face temporary setbacks, but history ultimately moves in the right direction."

A new book on Kim Dae-jung (1924-2009) marks the centenary of the birth of the country's 15th president and Nobel Peace Prize laureate as well as the 15th anniversary of his passing on Sunday.

Over 780 pages long, "Kim Dae-jung Memoir -- What Does Kim Dae-jung Tell Us Today?" captures 42 hours and 26 minutes of oral interviews conducted with Kim between July 2006 and October 2007 by researchers from the Kim Dae-jung Presidential Library and Museum, offering a detailed account of his life, ideology and philosophy.

The interviews and their publication reflect Kim's belief in the importance of historical records, according to the researchers at the library.

"(Kim) was dismayed by the lack of archival records from previous administrations. He established laws to ensure meticulous documentation of governmental affairs, emphasizing the significance of preserving history," said Kim Sung-jae, chairman of the Kim Dae-jung Library Development Fund, during a press conference in Seoul on Aug. 13, the day of the release of the new memoir.

Kim recalled that the former president carried two notebooks -- keeping public and private records separately.

During his time in office, from Feb. 25, 1998 to Feb. 24, 2003, Kim Dae-jung enacted the Public Records Management Act in 1998, making it mandatory for public institutions to systematically keep and manage their records.

The memoir is seen as a textbook of modern South Korean history and democracy, according to the research team at the library.

The book chronicles Kim's journey from a student in Hauido, an island in South Jeolla Province, to 2007, shedding light on key periods of South Korean history. It covers his schooling in Mokpo, the Korean War, his political awakening during the April 19 Revolution against President Syngman Rhee, his relentless fight for democracy -- including six years of imprisonment, three years in exile, an abduction, a death sentence, and long periods of house arrest.

Kim's presidency was recognized by his response to the 1997 Asian financial crisis and the historic first-ever inter-Korean summit of 2000 which led to the June 15 Joint Declaration and his Nobel Peace Prize in 2000. The Nobel Committee honored him "for his work for democracy and human rights in South Korea and in East Asia in general, and for peace and reconciliation with North Korea in particular."

The book delves into Kim's policies and theories and recounts behind-the-scenes stories of overcoming the Asian financial crisis and his interactions with global leaders like former US President George W. Bush and former Japanese Prime Minister Junichiro Koizumi.

The book also includes over 60 photographs, featuring previously undisclosed photos, such as with Stephen Hawking, a next-door neighbor while Kim was studying at Cambridge University in the early 1990s.

"Unlike other autobiographies, we kept Kim's words intact as they were, making only minor edits for clarity. We were contemplating until the very end whether to release this material as an academic document or as a book. We decided to publish it as a memoir for the general public,” said Yang Jae-jin, director of the Kim Dae-jung Presidential Library and Museum. This is the first complete publication of Kim's oral interviews though parts have been previously revealed.

Yang explained that Kim meticulously prepared for each interview, reviewing written questions in advance to ensure accuracy. The entire process was also recorded on video, with QR codes in the book linking to the related video materials housed at the library.
