Seems to indicate that the more things change, the more they stay the same! About 10 years ago, findings within the health sector also suggested a need for teaching better approaches to literature searching.  The value of searching is suggested by Klein et al. -

Effect of Online Literature Searching on Length of Stay and
Patient Care Costs
ACADEMIC MEDICINE 1994;69(6):489-95
Despite important limitations, which are covered in the
discussion, this case-referent study in three teaching hospitals
demonstrates significant savings in length of stay and in cost
per case for 19 DRGs associated with a physician-requested
MEDLINE search performed by a medical librarian. Searches done
earlier were associated with lower cost and length of stay than
those done later.

When it was still being published, a review enlisted for CLINICAL PERFORMANCE & QUALITY HEALTH CARE described a much more effective way to approach literature searching than the approach usually taken by health care professionals. In "Where's the Evidence? How to Find Clinical-Effectiveness Information" (Clinical Performance and Quality Health Care 1998;6(1):44-48), Julie Glanville describes a "cascade" approach to make the most efficient use of literature archive indices.
