The document discusses a method called "counting the traffic" that libraries can use to gather data on user activities and behavior within the library. Observers record how many people they see engaged in different predefined activities at regular intervals while walking through the library zones. Analysis of data collected from several Norwegian libraries found that digital and social activities were more common than expected, comprising over 40% of behaviors in many libraries. The method provides insights beyond circulation data and can help libraries understand how space is used.
