Works printed in Great Britain and North America as English-language works printed elsewhere. This collection of more than 5,600 titles encompasses all possible fields, but is particularly well stocked with works concerning (Dutch Reformed) Protestantism in Great Britain, the Netherlands and America, and the exchange of ideas between those countries.

Key among these are Bibles and psalm books, and works by John Bunyan and John Milton. A large part derives from the library collections of New College in London and Columbia Theological Seminary in Decatur (Georgia, USA), which were acquired in full and therefore also contain non-English editions. The books from both collections are recognizable by a stamp and/or pasted-in ex-libris. The H. Bos library also contains many rare English editions.

Such a large collection of English editions is unique in the Netherlands.
