"OCLC has implemented a data visualization pilot project in conjunction with Antarctica Systems Inc. (http://antarctica.net) to evaluate library users’ experiences with searching and display of search results using a visual interface to the Electronic Books database on OCLC FirstSearch.
.... For the purpose of this pilot, users will be searching in a static database of about 211,000 electronic book titles. The pilot will run through April 5, 2005." from a promo e-mail from OCLC
