ABSTRACT
SUMMARY. This article builds on Professor Penny Hazelton’s examination of “how much of your collection is really available on Lexis and Westlaw?” While Hazelton examined the question from the perspective of space occupied, Professor Chiorazzi looks at the question from the perspective of collection use. Using the economic theory called the Pareto Principle, Chiorazzi argues that over 80% of the use of all legal materials is accounted for by the 20% of all legal materials that are available online. This has significant implications for law librarians seeking to expand or build new facilities. The legal research environment has changed to a point where most research can in fact be done online and large research paper collections may become harder to defend against administrators using potentially shortsighted cost-benefit analyses while making library budgeting decisions.
