the failure of the digital model

Oddly, it's a failure of modern devices to adapt to electronic content. For books, this means that your reader needs to comply with one or more of these formats: EPUB, Kindle, PDF, Plucker, QiOO Mobile, and Plain Text. (This is based on the file selection for texts from Project Gutenberg.)

But paper adapts fantastically. We have paperback, hardcover, oversize books, pamphlets, large print books, tiny pocket books, spiral bound books, weird font books, picture and board books, smooth glossy photographs, textured pages, braille, deckle edges, ... pretty much any form that paper can take can be used to display print and images.

Can I fit a large format world atlas in your iPad? Not without losing the entire perspective of the area. Sure, you can zoom in with any level of detail or scale or at any angle, but does a 30" map really work better on a 6" x 9" screen?

Digital is restrictive. Ironically, when it comes to sharing, electrons are rigid and paper is fluid.

The Google Generation & the Digital Transition

An interesting study was commissioned by the British library and the Joint Information Systems Committee (JISC) identify how specialist researchers of the future, currently in their school years and preschool years are likely to access and interact with digital resources in 5-10 years time. Additionally, the study is to assist library and information services to anticipate and react to any new or emerging behaviors in the most effective way.
The report defines the "Google Generation" as those born after 1993.
The study was to establish whether or not as a result of digital transition, the "Google" generation are searching for and researching content in new ways; and whether it is likely to mold their future behaviors as mature researchers. Additionally, whether or not,new ways of searching content will be any different from the way researchers & scholars carry out their work.
Moreover,research libraries face a great deal of challenges today in the digital marketplace. Today, they're adjusting to facebook.
Additionally,the study found the the "Google" generation and information literacy of young people,has not improved even with more access to technology. Young people spend little time evaluating information. Young people have poor understanding of their information needs. As a result, they exhibit a strong performance for expressing themselves in natural language rather than analyzing which key words might be more effective/
Finally the study suggests that print sales will diminish drastically as blogs, RSS,media players, and podcasting devices become established.
