Unfortunately, with Gaddafi it's a case of a lot of the older material being a lot better in quality than some of the newer publications. In fact a lot of the newer stuff, like Kawczynski's biography, largely consists of rehashed information gleaned from those older biographies. Now that Gaddafi's dead and Libya is a representative democracy, I hope that historians will be able to work more freely over there and produce some fantastic biographical and historical studies of Gaddafi and his regime. If and when that's the case, then I shall be sure to make ammendments to the article.
