That said, I notice that I am not listed among the contributors on the publisher's page ;-)
This collects the proceedings of the first M-Libraries conference. I have agreed to speak at the successor conference, The 2nd International M-Libraries Conference, in Vancouver in June 2009. A call for papers is posted on the conference page.
This conference aims to explore and share work carried out in libraries around the world to deliver services and resources to users 'on the move,' via a growing plethora of mobile and hand-held devices. The conference will bring together researchers, technical developers, managers and library practitioners to exchange experience and expertise and generate ideas for future developments.
