The British Library has just launched an online interactive literary map to coincide with its major summer exhibition, Writing Britain: Wastelands to Wonderlands. The exhibition takes visitors on a journey of literature across the British Isles, showcasing treasures ranging from John Lennon's original lyrics for The Beatles 'In My Life', J K Rowling's  handwritten draft for the first Harry Potter novel and original manuscripts from the likes of Jane Austen, Charles Dickens and Arthur Conan Doyle.

The public have been invited to take this landscape-inspired collection 'beyond the walls' of the exhibition with an interactive project named 'Pin-a-Tale'. Anyone can choose a literary work from any period and in any form, and 'pin' it to the literary map online. Fans of Led Zeppelin , for example, can 'pin' the song about an obscure Welsh cottage onto the map (at Bron-yr-Aur) while J R R Tolkein experts can compare The Two Towers and Leed's Tower Works.  All entries will then be archived to the Library's digital collections and the curator's favorite submissions will be displayed on a digital projection of the map as part of the physical exhibition.

Like Dazed and Confused's 'A Secret History of East London' we featured back in April, this is a great example of a crowdsourced psycho-geographical project that is both engaging and a useful resource for the future. Pin your tale here.
