A graphic novel biography of US presidential candidate Barack Obama is now available to download on to mobile phones. US specialist uclick will offer a mobile version of Presidential Material: Barack Obama from 8 October. Not to be outdone, Obama’s rival in the race to the White House, John McCain will also have a Presidential Material biography available to put on to mobile phones.

Mobile books have yet to take off, perhaps due to the fact that most post-1995 mobile phones don’t have enough screen size to accommodate much of a book’s page. However that’s no deterrent to websites such as MobileBooks.org from offering paperback downloads for phones though.

The website contains handy instructions for navigating your way round mobile books, with different number keys providing shortcuts to move between pages, chapters and key words. The site has over 20,000 mobile books to choose from.
