Communication is imperative for interaction, knowledge construction, and mediation of information. When interacting with the library using communication devices in the social web to obtain access to information, the person has the ability not only to identify and locate information, but also to discuss and exchange of information collectively, and perform and develop practices that enhance mental operations of the content accessed. Thus, this study presents features and possibilities for university libraries to use communication devices in the social web to integrate information activities. Therefore, we applied technique of content analysis to conduct a bibliographic study to identify and analyze surveys and studies on the subject in Information Science. As a result, we identified the different uses of these devices and their potential application within the university library and concluded that the adoption of different types of devices requires the analysis of the specific objectives for each activity, service or product that the library wishes to develop, as well as the user profile and the technological infrastructure available. However, in view of the mission of the university library, it was concluded that we need to rethink the process of communication and interaction with users of information in order to use these communication devices in the social web in a broader and more efficient way.
