Dolly Parton was honored by The Library of Congress this year to mark a little known milestone in her life— the 100 millionth book that she has quietly donated to children.

The ‘Nation's Library' in Washington D.C. highlighted the singer-actress's nonprofit, "Imagination Library", which she began more than two decades ago with the goal of giving books to kids around the world.

"Of all the things I've done in my life, and it's been a lot 'cause I've been around a long time, this is one of the most precious things and the proudest I am of any program," Dolly told the gathered audience of wee ones and adults.

She engaged the audience during the celebration by reading—and singing—her children‘s book created from her song, "A Coat of Many Colors," about a child who treasured a coat that her momma quilted from rags.

Known by the children who received her gifts as "The Book Lady", she started the program to honor her father, who couldn't read, yet was the "smartest man" she every knew.
