Negative externalities More users is not always positive El Farol Bar problem 60 seats > 60 guests will ruin fun for everyone Not going = 0 payoff Going with <= 60 people = positive payoff But going with too many people = negative payoff Traffic jam Too many users could overload network or systems Equilibrium will find itself through changing expectations of users

Doe” or “John D.” Solution: linking algorithms using meta-data, co-authors,... Consistent Reference Services: bundles URIs about same subject in some context (eg. ReSIST) e.g. Some institution about some person Okkam: centralized CRS Network-based production needs control mechanisms Wikipedia disambiguation page
