What is the author's style in the Unfinished Tales of Numenor and Middle-earth?

Many of these tales are written in a style similar to a reference text rather than a typical fictional tale. For the most part, these stories are written to provide supplemental information to Tolkien's major works. Knowing these different pieces of information makes the overall experience much more vivid and real. The reader can see the same story from several different points of view, and therefore understand the mindset of all of the players involved.
