Two of Britain's national libraries have exchanged poems as a way of celebrating a centenary.
This year marks the 100th anniversary of the National Library of Wales. The NLW commissioned Gwyneth Lewis to produce two poems to national and research libraries across the world. One is in Welsh, the other in English and they are similar, though not identical.
To return the compliment, the National Library of Scotland commissioned Stewart Conn to write a poem expressing centenary greetings. Conn was Edinburgh's first official 'makar' (poet).
