Founded in 1973 and acquired by ProQuest Information and Learning in 1999, Chadwyck-Healey was long known as a leading publisher of innovative scholarly reference and full-text materials, remarkable in their content and the quality of their indexing and abstracting.

Today the Chadwyck-Healey brand is an integral part of the ProQuest CSA family, with microform and electronic offerings for schools, universities, government departments, and companies around the world. Our Chadwyck-Healey resources provide quick and easy access to large collections of authoritative information and deep archives of primary material.

The Chadwyck-Healey product line includes more than 40 key digital resources for students, scholars, and teachers of the humanities and social sciences, as well as extensive reference resources. They range from relatively small databases, such as Kafkas Werke, to very large collections such as English Poetry, which makes a substantial part of the poetic corpus in English of the last 14 centuries available in electronic form. Many Chadwyck-Healey resources combine numerous individual databases or sources of information to form larger and more comprehensive Web gateways like Literature Online and C19: The Nineteenth Century Index.
