1. EVALUATION
OF DIGITAL
LIBRARY

2. Criteria in DL evaluation
•in DL: no basic or
standardized criteria, no
overall agreement

3. In digital libraries:
•performance (effectiveness, efficiency)
on basis of given criteria
•performance could be related to
usability.
•The performance of the system
depends strongly on the formats,
structures and representations of
the content.

4. • Usefulness
---which concerns the “User” and
“Content” components. The usefulness
of the content and its relevance to the
user tasks and needs are the reasons
behind the selection and usage of a DL.
This relevance is translated into actual
relevance, type and level of resource
relevance and task relevance.

5. 5
USABILITY
•International Standards
Organization - ISO 9241-11 (1998)
•“Extent to which a user can achieve
goals with effectiveness, efficiency
and satisfaction in context of use”

6. 6
• Jacob Nielsen (usability guru)
• definition:
“Usability is a quality attribute that
assesses how easy user interfaces are
to use. The word "usability" also refers
to methods for improving ease-of-use
during the design process.”

7. Six Classes of Criteria for DL
Evaluation Derived From Literature
•content
– how well are digital collections
selected, developed; objects created,
organized, represented, presented

8. • technology
• how well do hardware & software
support library functions
• Interface
– what is available for users to
interact & how much is interaction
supported or hindered
8

9. • Process/Service
– what processes & assistance are
provided; what range of services is
available; how well are they
functioning; (carrying out tasks as:
search, browse, navigate, find,
evaluate or obtain a resource)

10. • user
– what are the outcomes of DL use –
changes in human information
behavior, cognitive state, decision-
making, problem-solving; impact on
accomplishing tasks; broader
impact/benefit in research,
professional work

11. •context
– how well does a DL fit into,
respond to, follow larger
context – institutional,
economic, legal, social,
cultural; effects on context
