George Offor

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.

John Bunyan
He had compiled the complete works of John Bunyan. However some of them were destroyed in a fire.

He spent his days reading, researching, recording, comparing, and editing the works of Bunyan. Offor's diligent labour 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.

Auction
After his death, his huge collection of books was to be auctioned on 27 June 1865, for 11 days by Sotheby's. However, on 29 June, a fire consumed nearly all the items that were for sale.
