Teach Yourself
Teach Yourself is an imprint of Hodder Education and formerly a series published by the English Universities Press (a subsidiary company of Hodder & Stoughton) that specialises in self-instruction books. The series, which began in 1938, is most famous for its language-education books, but its titles in mathematics (including algebra and calculus) are also best-sellers, and over its long history the series has covered a great many other subjects as well.
