A book exchange is now operating five days a week under the railway arch in Union Street.
The Rocketvan Boxshop Book Swap is the latest initiative of the cardboard box shop opposite the Union Theatre.
The shop, specialising in packing materials, has a smart library trolley which is already gathering books.
"Feel free to take one, leave one or both!" says a notice.
Donations and replenishments are welcome.
• Another permanent local book exchange operates at Absolutely Starving in Tooley Street.
