Books donated to Oxfam shops including two rare finds from shops in Suffolk, are being auctioned in a bid to raise £40,000 for the charity.
Highlights of the auction include a 1732 edition of Milton's Paradise Lost, which was found in Bury St Edmunds.
Also under the hammer is a first edition of Virginia Woolf's The Waves, found in Woodbridge.
The auction will take place at Bonhams in Oxford on 16 June and is part of Oxfam's first national book festival.
Last year's Oxfam auction featured the very first appearance in print of Sherlock Holmes which sold for £15,500.
The Victorian Journal featuring the Sherlock Holmes story was spotted by an Oxfam volunteer.
As part of the Oxfam Bookfest festival, from 4 to 18 July, more than 280 book-related events will take place all round England.
