In keeping with the writing style and the overall horror theme, it would be interesting to have some form of narration in the ufopedia. Think of something inspired from one of the earlier Mass Effect games where you would load up an information screen and you can read it but the system had a narration by some librarian that went along with it. Sort of like taking live computer training on a subject.
The reason for including this is controlling the ambiance. Narrators tone or reflection can imply their bias on the impact or meaning of what you're reading while simultaneously producing a mood or feeling from the reader. If the outcome of research is something trivial in the library the narrator (be it a computer, or perhaps acting as a recorded message by one of your specialists) would narrate in such a way you could tell they felt the subject trivial. However, if the information is of more concern, urgent, scary or important, that can be reflected in the narrator's tone. You can even use different narrators based on the discipline or even conflicting narrators. Sort of a video or audio log from your trusted advisors on each subject. Each providing their own take on the same information.
Obviously, this is "cosmetic" but could really add some flavor to the game, and even perhaps provide a connection to your advisors (if you have any) as you get to know their personalities and biases.
