I used Random.org in 2004 to create a sample of bibliographic records in OCLC WorldCat for a demographic study of that bibliographic database. The results were published in my article, ‘From the Ubiquitous to the Nonexistent: A Demographic Study of OCLC WorldCat,’ Library Resources & Technical Services 50 (2): 79-90, Spring 2006.
I have since taken two samples for further studies of WorldCat.
