Reddit use in the LIS community.

This study examined online communications within library and information science (LIS)-related subreddits through the perspectives of social identity theory and social media engagement. A total of 17,049 Reddit posts from three major LIS-related subreddits were harvested through Pushshift by Python. Manual and computational coding methods were used to identify linguistic characteristics of the posts as well as the topicality of the content. Multiple logistic regressions were used to analyze the relationship between psychological and emotional characteristics of the posts and user engagement. Results showed that the majority of posts did not mention a specific type of LIS organization; of the subset that did, public libraries and academic libraries were most frequently referenced. “Library services and usage” was the topic most mentioned within LIS-related subreddits, followed by “librarians and jobs.” Various psychological features of posts including emotional tone score, authentic score, clout score, analytic score, and usage of words related to affective processes, anxiety, social processes, causation, and time were significantly related to user engagement. This study contributes to further understanding of social identity theory and social media engagement within the online communication context of LIS community. Key topics and issues in the LIS field and practical suggestions for strategies to improve social media engagement across LIS community were discussed.
