This paper attempts to highlight the factors causing anxiety among non-native speakers of English when using academic library resources, services and facilities. This is crucial now that academic libraries worldwide are increasingly building up their collections of electronic journals and databases, which are predominantly in the English language. Findings from studies among non-native speakers of English reveal that they are susceptible to anxiety factors, which are rarely reported in studies in the native English-speaking countries. Some of these barriers include: insufficient resources, language, retrieval, lack of library skills, technology, network, environment and services, computer and physical comfort, and emotional barriers. A search was conducted to analyze the literature published in Library and Information Science Abstracts (LISA) from 1986 until 2014 using the keyword ‘library anxiety’. The sample selected was limited to literature on non-native speakers of English. The distinct anxiety-causing factors typically reported in these studies are recommended to be included in the library anxiety measure for future research.
