This document discusses the concept of information sharing as an obligation of citizenship. It outlines different models of citizenship, including republican and liberal traditions, and notes tensions between sharing information and protecting privacy. The document uses the example of eBird, a citizen science project where birdwatchers share observations, to illustrate how data sharing can benefit scientific understanding but risks losing public trust if seen as mandatory. It concludes by arguing information professionals should promote education on responsible data sharing and help connect data sharing to improved e-government.
