Family Guy creator Seth MacFarlane has donated a large collection of Carl Sagan's papers to the Library of Congress, where they will be preserved alongside works by Benjamin Franklin, Thomas Edison, Sigmund Freud, and many other important historical figures. MacFarlane provided the funds that enabled the Library to obtain some 800 boxes of documents that include book drafts, "idea files," correspondence, and even childhood report cards, notebooks, and drawings. "We are honored to preserve and make accessible to researchers the legacy of Carl Sagan, a man who devoted his life to the study of the universe," said Librarian of Congress James Billington. Space.com has more on Sagan's legacy, his influence on MacFarlane, and the new series Cosmos: A Space-Time Odyssey, which is expected to air next year.
