Here is a look at some of the stories that CNN plans on covering this week:
Martin Luther King Jr. documents go online
Monday is Martin Luther King Jr. Day, one of 10 national holidays in the United States.
Besides marking the day as a federal holiday for the 26th time, January 16, 2012, begins a new age of online accessibility for those wanting to know more about King and his work.
The King Center Imaging Project, which makes 200,000 ofÂ the civil rights leader's documents quickly accessible online, goes live Monday. King's "I Have a Dream" speech, his Nobel Peace Prize acceptance speech and his letter from a Birmingham, Alabama, jail are among the documents available.
The Martin Luther King Jr. Center for Non-violent Social Change in Atlanta and JPMorgan Chase & Co., working in partnership with AT&T Business Solutions and EMC, are responsible for the project.
Taking King at his words
The memorial to Martin Luther King Jr. has sparked controversy, and perhaps this is fitting. He was a controversial man whose humanity - and words - still speak volumes today.
CNN's Todd Leopold takes a look at this for a story that will hit the CNN.com homepage on Monday. But Ahead of the Curve readers can get a sneak peek at the story here.
'Roots' cast reunites
Thirty-five years after appearing in their groundbreaking television miniseries, the cast of "Roots" reunites in an 8 p.m. ET special on OWN, the Oprah Winfrey Network.
"Roots," a 12-hour miniseries, ran on ABC from January 23 to January 30, 1977.Â It was based an author Alex Haley's novel about his ancestors journey from enslavement in West Africa to emancipation during the Civil War.
At the time, "Roots" scored higher ratings than any TV program in history.
"The show defied industry conventions about black-oriented programming: executives simply had not expected that a show with black heroes and white villains could attract such huge audiences," according to the Museum of Broadcast Communications.
LeVar Burton and John Amos, who shared the role of lead character Kunta Kinte, are among those appearing with Oprah.
GOP leaders gather in South Carolina
The Southern Republican Leadership Conference begins Wednesday in Charleston, South Carolina.
The event is expected to attract more than 2,000 GOP elected officials, representatives from business and the media, activists and donors as well as the candidates in South Carolina's Republican presidential primary on Saturday.
On Thursday evening, the candidates will participate in a CNN-sponsored debate at the event.
The keynote address of the conference will be delivered Thursday by former GOP presidential candidate Herman Cain, the businessman who quit his campaign in early December after battling allegations of past sexual harassment.
Cain told CNN's Wolf Blitzer in earlier this month that he would make an "unconventional" endorsement in his speech.
Sundance Film Festival begins
The 2012 Sundance Film festival begins Thursday in Park City, Utah. Sex surrogates, happy drunks, not-so-happy drunks, teenagers in love, a little boy on a gangland odyssey and a trio of time-travel investigators are just a few of the movies in the competition line-up.
Sundance traces its origins to to 1981, when actor/director Robert Redford gathered friends, colleagues and 10 emerging filmmakers to develop projects without the commercial pressures of Hollywood.
Among the films to come out of the festival over the years are "Little Miss Sunshine," "An Inconvenient Truth," "Reservoir Dogs," "American Splendor" and "The Cove."
Kennedy hearse to be auctioned
The 1964 Cadillac hearse that carried the body of President John F. Kennedy from a Dallas hospital to Air Force One at Love Field after Kennedy's assassination on November 22, 1963, goes up for auction in Arizona on Saturday.
â€śThe eyes of the world were on this car on that unforgettable day in American history,â€ť said Steve Davis, president of Barrett-Jackson, which is conducting the auction in Scottsdale. â€śItâ€™s one of the most significant and historical vehicles ever offered for sale.â€ť
The hearse was purchased by the O'Neal Funeral Home in Dallas just a few weeks before the funeral home was asked to supply a casket for the president and take his body from Parkland Memorial Hospital to the airport for the final trip to Washington.
According to Barrett-Jackson, Arrdeen Vaughan, believed to be an employee of the funeral home, bought the hearse in the late 1960s and kept it for more than four decades before selling it to an unnamed party, its current owner.
Last year, an ambulance that was reportedly used to transport Kennedy's body from Air Force One to Bethesda Naval Hospital in Maryland was sold at auction for $132,000. The price could have been higher but doubts over whether it was the correct vehicle kept the price down.
