The Butler Collection is a collection of children's literature which had been created by Mary Thwaite and further developed by Joan Butler, both librarians for Hertfordshire Library Services. It was jointly acquired by the Robinson Library and Seven Stories, the Centre for Children's Books.The collection includes eighteenth-century pamphlets and books such as Young, Rev. J. The perils of Paul Percival or the Young Adventurer (c.1841), Ballantyne, R.M. The gorilla hunters: a tale of the wilds of Africa (1897), Banks, A. Cheep and chatter or lessons from field and tree (1884) and works by such well-known children's writers as Hans Christian Andersen, J.M. Barrie, Frances Hogson Burnett, James Fenimore Cooper and Daniel Defoe as well as books illustrated by Randolph Caldecott.

The Burnett Collection of children's literature was presented by Professor Mark Burnett (Queen's University Belfast) and contains books and annuals which were mostly published in the early to mid-Twentieth Century. It includes such titles as: Timothy's quest (1900), The boy's adventure book (1935), The Flying Five and other stories of adventure and school life (1936), and Girl's fun annual (1952).

Brian Alderson (b. 1930) is a pioneer of children’s literature studies in Britain as a distinguished author, reviewer, and translator. He has also collected books for more than 60 years, beginning when he was an undergraduate with cheap editions of work by poets Ezra Pound and T.S.Eliot. His interest in children’s books came later but soon became a lifelong passion, resulting in the curation of a collection of over 20,000 books, dating from the 17th century to the present day. This collection, donated jointly to the University and Seven Stories: The National Centre for Children's Books, represents a vast and diverse distinctive resource.
