Like in any endeavor, adoption and use of social media requires planning. However, this is not the case in Zimbabwe. To assess the situation, a study was conducted among different type of libraries in the country. Purposive sampling technique was adopted. The objectives were to find out the libraries which had social media strategic plans, and, among those which had none, to establish the extent to which social media use policies and principles corresponded to the basic strategic plan model. Results indicated that adopted tools include Facebook, Wikis, YouTube, Blogs, Twitter, Skype, Flicr, Ning, and LinkedIn. Reasons for adoption included being trendy as well as to enhance the library's efficiency, and goals included to continuously avail information in a variety of formats to clients within a short space of time and to effectively market library services. However, no library had a written social media strategic plan. The principles and policies for using social media covered strategies for implementation, surveillance, and monitoring of platforms for accountability.
