Of course, Lisa did not necessarily

intend to read his books. She might

want the computer only to write her

midterm. But Dan knew she came from

a middle-class family and could hardly

afford the tuition, let alone her reading

fees. Books might be the only way she

could graduate

Research in analysis (i.e., the evaluation

of the strengths and weaknesses of

computer system) is essential to the

development of effective security, both

for works protected by copyright law

and for information in general. Such

research can progress only through the

open publication and exchange of

complete scientific results
