Better than Brief Tests: Coverage Power Tests of Collection Strength by Howard D. White

Better than Brief Tests: Coverage Power Tests of Collection Strength by Howard D. White was the last article in the March 2008 C&RL issue that I didn't get to in my last review of the journal.  This was a pretty long article on a topic that I am recently interested in exploring: assessing collection development.  It does open with the disclaimer "When this article was first submitted, WorldCat users could easily perform coverage power tests as described below.  They cannot now...", which leaves me wondering if I can try to repeat the Methodology at all.  I hope so, this is a very good article on what comparing holding lists with OCLC really can mean, when the quantitative data is most meaningful, and the author is an experienced expert on the process.  A good background read, but perhaps less a less practical example.
