The Oxford Companion to Children's Literature is a reference work first published in 1984, with its most recent edition in 2015. The Oxford Companions is a book series providing general knowledge within a specific area,[1] in this case, children's literature.
The first edition of Companion, by the husband-and-wife team of Humphrey Carpenter and Mari Prichard,[2] was published by Oxford University Press in 1984.[3] Iona and Peter Opie originally intended to write the Companion but did not complete it.[4] Although they consulted with others, Carpenter and Prichard wrote each entry themselves.[5] In about 2,000 entries,[6] it covers children's books and folklore from the Commonwealth, United States, and some other countries.[3][7]
Daniel Hahn's updated edition of the Companion was published in 2015.[2][8] Its longest entry is on Harry Potter.[2]
