Beside students, there is a possibility that those teachers and
researchers who specialize in some scientific fields are not
sensitive to information acquisition. When they begin to use a
new or old information resource, they always ignore all the
description and instructions .At this time, they often consult
with librarian in the library of college. If they don’t remember
the answer again, maybe they will give it up. And when
schools are far away from the places those readers live in, they
can’t review the skills of information retrieval and get their
information requirements satisfied.
