5. Scenario
• Alice has purchased an Chemistry ebook that was
recommended by her course tutor
• She travels to school on the bus and may wish to read the
ebook on a pda or other such portable device.
• Later at school, she may want to quickly refer to some of
the diagrams found in the ebook in more detail on a PC
with a large screen.

6. Scenario
• At home, while writing a report she may wish to cross check
some of her own notes with the ebook again, but this time
using a laptop.
• Still at home, a friend on her community network has asked
her a Chemistry question which she would like to answer in
part by sharing some information from her ebook.
• After the course examinations, the student would like to
transfer the ownership of the ebook to her younger brother.

Critics claim that is imposible to solve the
●
problem
Using social networks is an attempt to

make it more consumer friendly whilst
leaving enough control for content
distributors
