Benson, Amy and Robert Favini, "Evolving Web, Evolving Librarian," Library Hi Tech News, no. 7, 2006, pp. 18-21.

Representative of many articles and blogs that embrace the idea of libraries relaxing data privacy standards to make the library search experience more like Amazon or other similar services. Like most other treatments of the subject, this article does not mention anything about informing users how personal data they provide will be used or even educating them about how information they provide to other sites which use social software can be used to track purchases, etc.
The authors mention several solutions--also mentioned in other sources--of tailoring the OPAC so the increasing number of people who use phones and other small-screen portable devices can make better use of the catalog and services such as ILL.
Essentially, they seem to be claiming that libraries either loosen their data privacy standards or they'll be on the fast-track to extinction.
