Academic library always emphasis collaboration with others, therefore since the very beginning of providing game services, libraries noticed the importance of partnership and collaboration with a wide range of related groups. Hence we could find a great number of examples of collaboration of game services. But the existing literature mentioned the collaboration topic scatteredly and these articles are lack of general overview discussions. So in this paper, we sort the collaborators to several categories, and would like to analyze cases as many as possible to illustrate how libraries and collaborators work together and how they successfully facilitate a better experience of game services. We finally find that different collaborators bring different benefits and libraries have better choose their collaborators based on different situations, and these efforts are all good attempts which provide examples for those libraries who are novice on providing game services.
