Doctor Who Discovers (series)

Doctor Who Discovers refers to a real-world series of books, as well as an in-universe series of books.

Real World
Doctor Who Discovers was a short-lived series of large format stapled paperback titles from Target Books published in 1977-78.

Although not strictly speaking part of the series the title The Doctor Who Dinosaur Book, published in 1976, established the format.

The series was intended to run to 24 titles, but only five titles were released in the Discovery series, with The Miners, Inventors and Pirates due next for publication before the range was cancelled due to poor sales.

Each of the books included a pull-out poster stapled to the centre depicting the cover artwork.

In-Universe
Doctor Who Discovers was a series of children's books apparently written by the Doctor during his time working with UNIT. The intended title for the series was The Doctor, Who Discovers... but 'some idiot' at the publishing company misprinted the title, resulting in the Doctor being credited as "Doctor Who".
