     Tim Richter and his wife, Linda, had taught for over 30 years near Buffalo, New York-he

in computers, she in special education."Teaching means everything to us." Tim would say.In

April 1998, he learned he would need a heart operation.It was the kind of news that leads to

some serious thinking about life's purpose.

     Not long after the surgery, Tim saw a brochure describing Imagination Library, a program

started by Dolly Parton's foundation (基金会) that mailed a book every month to children

from birth to age five in the singer's hometown of Sevier, Tennessee."I thought, maybe Linda

and I could do something like this when we retire." Tim recalls.He placed the brochure on

his desk as a reminder.

Five years later, now retired and with that brochure still on the desk, Tim clicked on

imaginationlibrary.com.The program had been opened up to partners who could take

advantage of book and postage discounts.

     The quality of the books was of great concern to the Richters.Rather than sign up

online, they went to Dollywood for a looksee."We didn't want to give the children rubbish."

says Linda.The books-reviewed each year by teachers, literacy specialists, and Dollywood

board members-included classics such as Ezra Jack Keats's The Snowy Day and newer

books like Anna Dewdney's Llama Llama series.

     Satisfied, the couple set up the Richter Family Foundation and got to work.Since 2004,

they have shipped more than 12,200 books to preschoolers in their area.Megan Williams,

a mother of four, is more than appreciative:"This program introduces us to books I've

never heard of."

     The Richters spend about $400 a month sending books to 200 children."Some people

sit there and wait to die." says Tim."Others get as busy as they can in the time they have left."
