I can thoroughly recommend Susie Andretta's recent paper at IFLA "Transliteracy : take a walk on the wild side".
"In this paper we explore the concept of ‘transliteracy’ which according to Professor Thomas offers “a unifying perspective on what it means to be literate in the 21st Century [including] the ability to read, write and interact across a range of platforms, tools and media from signing and orality through handwriting, print, TV, radio and film, to digital social networks”. Currently transliteracy is primarily the domain of Communication and Cultural Studies and this paper aims to position transliteracy in the professional domain of ‘practising’ librarians and within the remit of the library world. ..... Examples of transliteracy practice by information professionals will provide evidence that libraries are already meeting the challenges of transliteracy by crossing the divide between printed, digital and virtual worlds to address the constantly changing needs of the learners they support."
She concludes with interesting interviews with leading practitioners Michael Stephens,Assistant Professor in the Graduate School of Library and Information Science at Dominican University in River Forest, Illinois (Tame the Web blog) ; Bernardette Daly SwansonReference, Instruction and Outreach Librarian, UC Davis Medical Center ; Sue Jennings, Outreach Librarian for the Lancashire Care NHS (National Health Service) Foundation Trust Library and Information Service ; Marja Kingma - Collection Manager, Collection Manager for Science, Technology and Medicine at the British Library.
