In 1923, Robert Frost gave his wife an inscribed copy of "New Hampshire," a work that later won him the Pulitzer Prize.
Now, the book and the prize diploma have been given to the University of New Hampshire by the late poet's family.
The gifts will help set up an archive at the university library dedicated to Frost and his wife, Elinor White Frost.
Among the gifts are Frost's Pulitzer Prize diploma for "New Hampshire," the 1923 work that won him the first of his four Pulitzers. The first copy of a limited edition of the book that Frost inscribed and presented his wife was also given to the university.
A patchwork quilt made from the academic hoods received by the poet, who died in 1963, also was given to the new archive.
The university also has the originals of six notebooks written by Lesley Frost Ballentine, the poet's daughter, detailing life on the family's Derry farm from 1905 to 1910, when she was 5-9 years old. The journals were published in 1969.
Frost once called the farm, his home from 1900-1911, "like a doctor's prescription" for writing his first three books.
Ballentine, one of the donors, said the journals "present a portrayal of a New England small farm of the period, but also show the parents as companions, teachers, botanists, astronomers, geographers and farmers."
The gifts were also given by the poet's granddaughter Elinor Frost Wilbur, a member of the Connecticut legislature, and other family members.
