Charles Sheffield wrote a novel based on this premise.
"[H]e devotes all his energies for a decade prior to his freezing, in becoming an expert primary source on the musically notable people of his era. Assuming that if you become the world's foremost expert in any subject, and given infinite time, someone will want to write a book on that exact subject."
If I recall correctly, the protagonist intentionally leaves tantalizing bits out of his books, so future historians will want to wake him up to ask him personally.
