If you're into buying old things off Amazon or Ebay, there was an entire series of Time Machine gamebooks in the 80s. Each one set you off on a specific mission: find the last living dinosaur, find the musket that fired the first shot in the American Revolution, learn who the Red Baron really was, find Panch Villa's death mask. Each one had you bouncing around in time gathering clues, until finally the mission was completed.
As I recall, there were about 25 books in the series, but to my knowledge it was never reprinted.
