Traditional "third places" provide physical places for human contact and social experience outside of the home or workplace/school. Institutions as disparate as fitness centers, libraries, and beauty salons are examples of third places: locations where people gather and often talk about things that are important to them. Libraries have a long tradition of connectedness and community that has put them in the forefront of traditional third places. As library Web sites are created and evolve, the sense of place provided by physical third places will become increasingly important online. Much about connectedness and community online can be learned from the concept of third places and their importance in real life and in cyberspace. The traditions inherent in libraries as physical third places provide predictions, projections, and inspirations for continued good service in the online presence of libraries.

New technologies increase the ability to capture and retrieve data about library usage patterns and users. Collecting, analyzing, and using patron data, however, may raise concerns among library users about their online privacy and how the data collected might be used

Social tagging enables librarians to partner with users to provide enhanced subject access. This paper quantifies and compares LC subject headings from each of 31 different subject divisions with user tags from Amazon.com and LibraryThing assigned to the same titles. The intersection and integration of these schemas is described and evaluated.
