Munro gained world renown for writing about everyday people.
"Here we have a world prize being won by someone who writes about housewives in Vancouver, booksellers in Victoria, bean farmers in Huron County and accountants and teachers and librarians -- ordinary Canadian people, and she turns it into magic," Gibson said.
Munro's most recent short story collection is titled "Dear Life." The New Yorker magazine, in an interview with her last year, said it includes "several narratives in which women in some way shake off the weight of their upbringing and do something unconventional."
She was asked whether it was "normal for girls from rural Ontario to go to university" when she did, noting that in her stories, there "is often a stigma attached to any girl who attracts attention to herself. ... "
"I was brought up to believe that the worst thing you could do was 'call attention to yourself' or 'think you were smart.' My mother was an exception to this rule and was punished by the early onset of Parkinson's disease. (The rule was for country people, like us, not so much for towners.) I tried to lead an acceptable life and a private life and got by most of the time OK," she said.
Munro was asked how she came to focus on short stories.
"For years and years I thought that stories were just practice, till I got time to write a novel. Then I found that they were all I could do, and so I faced that. I suppose that my trying to get so much into stories has been a compensation," she said.
Munro has said in the past that she wanted to stop writing but continued.
"I do stop -- for some strange notion of being 'more normal,' taking things easy. Then some poking idea comes," she said. "This time, I think it's for real."
Last year's literature prize
Last year, Chinese writer Mo Yan received Nobel Prize in literature. Activists interpreted it as a nod to the hungry literary tastes in modern China, which could help spark more freedom.
The beloved Chinese author -- whose pen name means "not talking" -- has captivated his countrymen by intertwining fantasy and gritty everyday life.
Mo plies his trade in a country where running afoul of party lines could lead to censorship. His work packs a punch, but he walks a fine line. He is considered a writer within the system and even has embraced official restrictions on writing.
And he's a Communist Party member who holds a vice-chairman spot in the state-sanctioned China Writers Association.
The Nobel Prize in literature has been awarded 106 times since 1901. In recent years, Munro has been mentioned as a contender, along with Japanese author Haruki Murakami and U.S. writer Philip Roth.
It is almost always awarded to one author and has only been shared four times, which stands in stark contrast to the science Nobels, which two or three scientists often share.
The youngest recipient was Rudyard Kipling, who is known for his work "The Jungle Book." He was 42 when he received the prize in 1907. The oldest was Doris Lessing, who received it at the age of 88.
Incidentally, many think Winston Churchill received the Nobel Peace Prize, but he did not. He was awarded the Nobel Prize in literature in 1953.
Swedish industrialist Alfred Nobel created the prizes in 1895 to honor work in physics, chemistry, literature and peace. The first economics prize was awarded in 1969.
Nobels this week
Two Americans and a German shared this year's Nobel Prize in physiology or medicine Monday.
Americans James E. Rothman and Randy W. Schekman, and German Thomas C. Sudhof were honored for discoveries of how the body's cells decide when and where to deliver the molecules they produce.
And on Tuesday, two men who predicted the existence of the Higgs boson particle 50 years before its discovery took the prize for physics -- Francois Englert of Belgium and Peter Higgs of the United Kingdom.
