The South Central Region of the National Network of Medical Libraries has a great webinar now available in their archives on the usage of mobile devices (smartphones, tablets and e-readers) in medical libraries.

It is great for medical librarians just getting started with mobile devices. Seasoned mobile device librarians might find some interesting bits of information in the PPTs, references, and usage examples.
