Oh, wait, that’s the null hypothesis. “Law libraries and their librarians have no value” also demonstrates that thinking or rethinking about value is a double-edged sword. What if the null hypothesis is proven to be true?
From this perspective it is clear that library associations will ignore the null hypothesis by publishing reports that identify value. See for example the FT-SLA report entitled The Evolving Value of Information Management And Five Essential Attributes of the Modern Information Professional (free registration required to download). This recent study identifies the perception gap between executives and information professionals in special libraries and identifies ways the latter group can demonstrate their value to the former group by the means of always illuminating case studies and an equally useful to-do list of recommendations.
And then, in the specific context of law libraries and their information professions, there is this:
The last several years have brought fundamental changes to the legal profession and business of law. These changes have served as an impetus for law libraries to transform their operations and services in varied and profound ways—and it is now imperative that law libraries demonstrate the value they bring in concise, measurable ways.
Instead of attempting to test the null hypothesis, AALL appears intent on spending money to prove the value proposition once someone offers an empirical methodology that only does half of the empirically sound task. For more, see the republished text of AALL’s Oct. 28, 2013 press release (source of the above quote) and commentary at 3 Geeks’ AALL’s RFP on Law Library Value Report.
Frankly, I think value is like porn. One knows it when one sees it by the impact it stimulates. Got a ruler to measure the null? — Joe
