CONTEXTUALIZING AND INTERPRETING COST PER USE FOR ELECTRONIC JOURNALS
MATT HARRINGTON AND CONNIE STOVALL
WHAT TO EXPECT…
• Brief overview of theory and problem(s)
• Brief overview of VT’s Serials Decision Database
• Examples of contextualizing data
• Interpretation of data
• Our POV, recommendations, discussion
2
DATA AND VALUE
• Increasing use of statistical and financial data to aid
with serials decisions
• Increasing use of data to demonstrate value of library
resources to university administrators
• What does cost per use, average cost, or return on
investment tell us about a resource’s value
• What does the data mean and how can we make it
more meaningful?

DETERMINING VALUE
• Classical economists
• Smith: “the toil and trouble of acquiring” a thing
• Marx (and Ricardo, more or less): duality in value
• Determined by use-value and exchange value
• Value as a social construct
VALUE OF INFORMATION
• Information as a different sort of commodity
• Cost-benefit analysis used increasingly
• Marks shift away from classical economics
• Intellectual/emotional value vs. practical value
• Use value and exchange value
• Contextualized cost per use
