of item-level described content,
compared to finding aid access:
Efficiency:
35% less time, 48% fewer clicks
Not surprising: finding aid provides more context.
Effectiveness:
Success rates 7.5% higher
Not surprising: no search-in-page function
or navigation box.
Satisfaction:
Preferred by a ratio of 3:1
Not surprising: these are novice users.

Conclusions
Don’t compare item level access to
finding aid access;
they aren’t comparable.
