    Abstract
    Social networking sites (SNSs) can encourage interaction among users. Existing research mainly focuses on the ways in which SNSs are used in libraries and on librarians' or users' attitudes towards these SNSs. This study focused on the flow of information via SNS interactions between librarians and users on library Facebook, Twitter, and Chinese Weibo sites, and developed an SNS user interaction type model based on these information flows. A mixed-method approach was employed combining quantitative data generated from the analysis of 1,753 posts sampled from 40 library SNSs and qualitative data from interviews with 10 librarians. Four types of interactions were identified: information/knowledge sharing, information dissemination, communication, and information gathering. The study found that SNSs were used primarily as channels for disseminating news and announcements about things currently happening in the library. Communication allowed open-ended questions and produced more replies. In Facebook posts, Chinese Facebook users generated less "likes" than English-speaking users. The comparison of data between Facebook-like and Twitter-like SNSs in different library settings suggested that libraries need to coordinate different types of SNSs, and take library settings and sociocultural environments into consideration in order to enhance and encourage user engagement and interaction.

    Abstract
    This study aims to identify the categorical characteristics and usage patterns of the most popular image tags in Flickr. The "metadata usage ratio" is introduced as a means of assessing the usage of a popular tag as metadata. We also compare how popular tags are used as image tags or metadata in the Flickr general collection and the Library of Congress's photostream (LCP), also in Flickr. The Flickr popular tags in the list overall are categorically stable, and the changes that do appear reflect Flickr users' evolving technology-driven cultural experience. The popular tags in Flickr had a high number of generic objects and specific locations-related tags and were rarely at the abstract level. Conversely, the popular tags in the LCP describe more in the specific objects and time categories. Flickr users copied the Library of Congress-supplied metadata that related to specific objects or events and standard bibliographic information (e.g., author, format, time references) as popular tags in the LCP. Those popular tags related to generic objects and events showed a high metadata usage ratio, while those related to specific locations and objects showed a low image metadata usage ratio. Popular tags in Flickr appeared less frequently as image metadata when describing specific objects than specific times and locations for historical images in Flickr LCP collections. Understanding how people contribute image tags or image metadata in Flickr helps determine what users need to describe and query images, and could help improve image browsing and retrieval.
