As part of the events to celebrate Edinburgh's being named the first UNESCO City of Literature, three versions of the book were made freely available (including being left on buses and in other public places) throughout February 2007. These three versions were:
- A new printing of the novel with notes by Professor Barry Menikoff.
- A retelling of the tale for children.
- A graphic novel version created by Alan Grant and Cam Kennedy. Translations of the graphic novel were also published in Lowland Scots and Scots Gaelic.
