Visitors to Hay's Galleria this summer are invited to pick up and drop off books at a new 'honesty library'.
As part of the London Bridge City Summer Festival, the owners of Hay's Galleria have set up a book exchange at the river end of the arcade.
If you have any spare books you would like to contribute you can contact [email protected] or to place them on the bookshelves yourself.
London Bridge City says that any books left at the end of the summer festival will be donated to a local charity shop.
Other book exchanges in SE1 can be found at Forster Communications in Southwark Street, outside the Union Theatre and in Gibbons Rents.
