George Offor (1787– 7 August 1864) was an English book-collector who accumulated a massive personal library.
Offor entered business as a bookseller at Tower Hill, London. He studied Hebrew, Greek and Latin and became an expert in sixteenth- and seventeenth-century English literature and theological writings.
He spent his days reading, researching, recording, comparing, and editing the works of Puritan John Bunyan. Offor’s diligent labor concluded in 1854 with the printing of the three-volume, 2,800 page Works of John Bunyan. Now over a century and a half old, Offor’s final product remains the most popular definitive collection of Bunyan in print.
