What is Sexy Codicology? An independent project that aims to expand interest and awareness of medieval illuminated manuscripts to the widest audience possible through social media. They discover and explore digitized special collections around the world, hunting for beautiful illuminated manuscripts which they share on Twitter, Facebook, Google+, Tumblr and Pinterest as well as their blog Sexy Codicology. They have also developed Maps of Digitized Medieval Manuscripts Available Online and Codicology where they explain the basics of the various types of manuscripts. And they have developed a manuscript app — the DMMapp — that links to more than 500 libraries in the world from which users can browse digitized manuscripts. DMMapp is open source and always looking for contributions in its development as well as additional library collections for new content.
