While Web 2.0 technologies provide benefits to academic libraries and their users, there is no empirical data on their actual impact within libraries. To improve the use of these technologies and library services, more needs to be understood about librarians' perceptions of Web 2.0 technologies. Additionally, many academic libraries have incorporated Web 2.0 features into their websites to involve users and solicit feedback, but little research has explored the extent and purpose of adopting such features. Examining the practices of top academic institutions could provide guidance to other libraries on optimizing the benefits of these technologies.
