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

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.

• 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.

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”

• 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.”

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

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

•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)

•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

•context– how well does a DL fit into,
